Answer:

Step-by-step EXPLANATION:

LET us ASSUME that 2+ROOT5 is rational

SO,

2+root5 = a/b

Root5 = a/b-2 =a-2b/b

But we know that root5 is irrational

So,

Our assumption was wrong

Therefore, 2+root5 is irrational

Hence proved

The ADJACENT angles of a parallelogram is supplementary i.e their sum is 180 DEGREE.

LET the angles be 3x and 2x.

then, 3x+2x=180degree

therefore,x=36degree

so larger angle= 3x=3*36=108 DEGREES

ANSWER:

Where are questions.

Step-by-step explanation:

If a and b are the TWO zeroes of the quadratic polynomial ax²+bx+c=0, then discriminant value be b²-4ac.

If b²-4ac>0, then equation has two real and distinct ROOTS.

If b²-4ac=0, then equation has two equal roots.

If b²-4ac<0, the equation has no real roots.

ANSWER:

I THINK OPTION B is CORRECT

GIVEN:

• Two NUMBERS are differ by 3
• Sum of greater number and twice the SMALLER number is 15

TO FIND:

• What is the smaller number ?

SOLUTION:

Let the larger number be 'x' and smaller number be 'y'

CASE:- 1)

❐ Two numbers are differ by 3

According to question:-

➸ x –y = 3

➸ x = 3 + y....1)

CASE:- 2)

❐ Sum of greater number and twice the smaller number is 15.

According to question:-

➸ x + 2y = 15...2)

Put the value of 'x' in equation 2)

➸ 3 + y + 2y = 15

➸ 3y = 15 –3

➸ 3y = 12

➸ y =

❮ y = 4 ❯

Put the value of 'y' in equation 1)

➸ x = 3 + 4

❮ x = 7 ❯

❝ Hence, the SMALLEST number is 4 and largest number is 7 ❞

Answer:

LET the ANGLE be 'x°'

The TWICE of its supplement = 280°

Step-by-step explanation:

According to the problem

x° + 280° = 360°

x° = 360° - 280°

x° = 180°

Therefore, the angle = 180°

LET x and y RECTANGLE. AREA =xy

ANSWER is 0.8%

A 3 by 4 RECTANGLE is INSCRIBED in circle. What is the circumference of the circle?

A) 2.5π B) 3π C) 5π D) 4π

Let ABCD be a rectangle inscribed in circle with centre O

As, we know that, The point of meet of diagonals passes through centre of circle.

So, BD and AC of diagonals

The diagonals of rectangle bisect each other

So,AO=OC=AC/2 = RADIUS of circle

DIAGONAL OF RECTANGLE=

NOW THE RADIUS OF CIRCLE WE GOT=5/2CM

CIRCUMFERENCE OF CIRCLE=2πr

=2×π×5/2

=5π

SO OPTION C) 5π✔️✔️✅

1)A rectangle is inscribed in a circle whose equation is x²+ y² = r² or

where r is the radius of the circle. The diameter d of the circle is the diagonal AC OR BD of the rectangle.

2)AREA OF A CIRCLE=πr²

3)CIRCUMFERENCE=2πr

4)AREA OF SQUARE=a². (a = side of square)

5) Perimeter of Square=4a. (a=side of square)

6)AREA OF rectangle=l×b. (l= length, b=

BREADTH)

7)Perimeter of rectangle=2(l+b)

Answer:

270 Or 234 as you have not MENTIONED the height of the Trapezium

Step-by-step EXPLANATION:

USE the formula 1/2×(sum of PARALLEL sides)×height.

Solution:-

If ( x + 3y , 5 ) = ( 6 , 2x + y )

Now we can WRITE

x + 3y = 6 ....(i)eq

2x + y = 5 ....(II)eq

Solving by using substitution method

Taking ( i ) eq

x + 3y = 6

x = 6 - 3y .......(iii)eq

TAKE ( ii ) eq and PUT the (iii)eq

2x + y = 5

=>2× ( 6 - 3y ) + y = 5

=> 12 - 6y +y = 5

=> - 5y = 5 - 12

=> - 5y = - 7

=> y = 7/5

Put the VALUE of y on (i)eq

x + 3y = 6

=> x + 3× ( 7/5 ) = 6

=> x + 21/ 5 = 6

=> 5x/5 + 21/5 = 6

=> 5x + 21 = 6 × 5

=> 5x + 21 = 30

=> 5x = 30 - 21

=> 5x = 9

=> x = 9/5

Answer:- x = 9/5 and y = 7/5
