7.

Check 7 + 3x is a factor of 3 x cube + 7 x

Answer»

Answer:

Step-by-step explanation:

CHECK whether 7 + 3x is a FACTOR of 3x3 + 7x

Solution: Apply REMAINDER theorem

=>7 + 3x =0

=> 3x = - 7

=> X = - 7/3

Replace x by - 7/3 we get

=>3x3 + 7x

=>3(-7/3)3 + 7(-7/3)

=>3(-343/27) – 49/3

=> (-343/9) – 49/3

This value is not equal to 0

So that 7 + 3x is not a factor of expression 3x3 + 7x

17.

The perimeter of rectangle is 13 cm and it's width 2 3bill no upon 4 cm find its length

Answer»

Answer:

15/4 cm

Step-by-step EXPLANATION:

WIDTH = 2*3/4 cm = 11/4 cm

PERIMETER = 13 cm

length =?

perimeter = 2(length + width)

=> 13 = 2(length + 11/4)

=> 13 = 2length + 11/2

=> 2 length = 13 - 11/2

=> 2 length = (26-11)/2

=> 2 length = 15/2

=> length = 15 / 2×2

=> length = 15/4 cm

1.If (k, 2), (2, 4), (3, 2) are the vertices of atriangle of area 4sq.units, then the value of k is write in solution

Answer»

ANSWER :-

→ k = 7

To Find :-

Value of k

Used Formula :-

$\triangle = \frac{1}{2} \bigg\{\sf{x_{1}(y_{2}-y_{3}) + x_{2}(y_{3} - y_{1} ) + x_{3}(y_{1} - y_{2}) \: } \bigg\} \\$

Explanation :-

25.	If each side of a triangle is increased by 6 cm, the ratio of the perimeters of the resulting triangle and the original triangle is 7:4. Find the perimeter of the original triangle
Answer» Original TRIANGLE :- Let each side of the triangle be x. Perimeter = SUM of all sides Perimeter = x + x + x = 3x •°• Perimeter of original triangle is 3x ___________________________ New triangle :- Each side is increased by 6cm, So each side becomes, = (x + 6) Perimeter = Sum of all sides Perimeter = x+6 + x+6 + x+6 = 3x + 18 ____________________________ Also, Ratio of perimeter of new triangle and original triangle is 7:4 So, $\frac{3x + 18}{3x} = \frac{7}{4}$ 4(3x + 18) = 7(3x) 12x + 72 = 21X 72 = 21x - 12x 72 = 9x 72/9 = x x = 8 ___________________________ Each side of original triangle = x = 8cm Perimeter of original triangle = 3x = 3(8) = 24 •°• Perimeter of orginal triangle is 24cm

25.

If each side of a triangle is increased by 6 cm, the ratio of the perimeters of the resulting triangle and the original triangle is 7:4. Find the perimeter of the original triangle

Answer»

Original TRIANGLE :-

Let each side of the triangle be x.

Perimeter = SUM of all sides

Perimeter = x + x + x = 3x

•°• Perimeter of original triangle is 3x

___________________________

New triangle :-

Each side is increased by 6cm,

So each side becomes, = (x + 6)

Perimeter = Sum of all sides

Perimeter = x+6 + x+6 + x+6

= 3x + 18

____________________________

Also,

Ratio of perimeter of new triangle and original triangle is 7:4

So,

$\frac{3x + 18}{3x} = \frac{7}{4}$

4(3x + 18) = 7(3x)

12x + 72 = 21X

72 = 21x - 12x

72 = 9x

72/9 = x

x = 8

___________________________

Each side of original triangle = x = 8cm

Perimeter of original triangle = 3x

= 3(8)

= 24

•°• Perimeter of orginal triangle is 24cm

30.

If a+b+c=12, a^2+b^2+c^2=70, ab+bc+ca=37, find a,b,c.

Answer»

Given : a² + b² + c² = 70, a + b + c = 12, ab + bc + ca = 37

To find : a, b and c

Solution:

(a + b + c)² = a² + b² + c² + 2(ab + bc + ca)

=> 12² = 70 + 2(37)

=> 144 = 70 + 74

=> 144 = 144

Hence 3rd Equation can be found if 2 Equations are given

Hence these 3 Equations are basically 2 Equations

and 3 Variable a , b & c

We can not solve 3 variables with 2 Equations

There can be many possible solutions

few are below :

a = √37 i b = -√37 i c = 12 ( a , b & c can VARY )

Verification

a² + b² + c² = -37 - 37 + 144 = 70 (i² = -1)

a + b + c = √37 i -√37 i + 12 = 12

ab + bc + ca = (√37 i) * (-√37 i) + (√37 i) 12 + (-√37 i) 12 = 37

Not ENOUGH Details to find Unique Solutions

we can choose any one value then find others

let say a = 0

=> b + c = 12 bc = 37

=> x² - 12x + 37 = 0

=> b & c = ( 12 ± √144 - 4 * 37 ) / 2 = 6 ± i

a = 0 , b = 6 + i , c = 6 - i

a + b + c = 12

a² + b² + c² = 0 + 36 - 1 + 12I + 36 - 1 - 12i = 72

ab + bc + ca = (6 + i)(6 - i) = 36 - i² = 36 -(-1) = 37

Hence if we assume one value we can get others

a = 1 => b + c = 11 & bc = 26

x² - 11x + 26 = 0

b & c = (11 ± √17)/2

a = 2 => b + c = 10 & bc = 17

x² - 10x + 17 = 0

b & c = (10 ± √32)/2 = 5 ± 2√2

and so on limit less solution

36.	The sum of two numbers is 36 and their difference is 9 . Find the two numbers.
Answer» ANSWER : Two numbers are 22.5 and 13.5 . EXPLANATION : GIVEN :- The sum of two numbers is 36 and their DIFFERENCE is 9. TO FIND :- Two numbers. SOLUTION :- Let the two numbers be x and y. Sum of two numbers= 36 Difference between two numbers=9 According to the question, x + y = 36...............(i) x - y = 9................(II) ★By elimination :- x + y = 36 x - y = 9 _______________ 2X = 45 → x = 45/2 → x = 22.5 ✪ PUTTING x = 22.5 in eq.(i)✪ x + y = 36 →22.5+y=36 → y = 36-22.5 → y = 13.5 Therefore, the two numbers are 22.5 and 13.5.

36.

The sum of two numbers is 36 and their difference is 9 . Find the two numbers.

Answer»

ANSWER :

Two numbers are 22.5 and 13.5 .

EXPLANATION :

GIVEN :-

The sum of two numbers is 36 and their DIFFERENCE is 9.

TO FIND :-

Two numbers.

SOLUTION :-

Let the two numbers be x and y.

Sum of two numbers= 36

Difference between two numbers=9

According to the question,

x + y = 36...............(i)

x - y = 9................(II)

★By elimination :-

x + y = 36

x - y = 9

_______________

2X = 45

→ x = 45/2

→ x = 22.5

✪ PUTTING x = 22.5 in eq.(i)✪

x + y = 36

→22.5+y=36

→ y = 36-22.5

→ y = 13.5

Therefore, the two numbers are 22.5 and 13.5.

The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the height of the prism.Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches? Round to the nearest tenth.
Answer» Width of the rectangular prism It is GIVEN to us that the volume of the rectangular prism is CALCULATED by the given formula :- v = lwh Where, v = volume l = length W = width h = height Now, In the QUESTION we are given :- v = 138.24 cubic inches h = 9.6 inches l = 3.2 inches w = ? SUBSTITUTE these values in the volume formula given :- 138.24 = 3.2 * w * 9.6 138.24 = 30.72 * w w = 138.24/30.72 w = 4.5 ⇒ The width of the rectangular prism is 4.5 inches.

The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the height of the prism.Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches? Round to the nearest tenth.

Answer»

Width of the rectangular prism

It is GIVEN to us that the volume of the rectangular prism is CALCULATED by the given formula :-

v = lwh

Where,

v = volume

l = length

W = width

h = height

Now,

In the QUESTION we are given :-

v = 138.24 cubic inches

h = 9.6 inches

l = 3.2 inches

w = ?

SUBSTITUTE these values in the volume formula given :-

138.24 = 3.2 * w * 9.6

138.24 = 30.72 * w

w = 138.24/30.72

w = 4.5

⇒ The width of the rectangular prism is 4.5 inches.
