x-26. In the Fig., ABCD is a rectangle.Its perimeter is given by(a) 2x - 2(6) 4x - 4(c) 4x - 2(d) 2x - 4

Answer»

4x-4 is perimeter of this rectangle.

4x-4 is corect answee

length of rectangle. = x-2breadth of rectangle. =. xperimeter of rectangle= 2(l+b) =2(x-2+x)=2(x+x-2)=2(2x-2)=2×2x-2×2=4x-4

I think that it's perimeter is 4x-4

correct answer is option no. (B)

b 4x-4 is the correct answer

Using formula,perimeter of rectangle=2(l+b)=2{x+(x-2)}=2(2x-2)=4x-4

(a) -1 (b)-1 (c)-2 (d)-2

4x-4 is correct amswer

4x-4 is the correct answer

0.833333...... it's a ans

b option is correct option

4x-4 is the correct answer of this question

Perimeter of rectangle = 2(l+b) = 2(x+x-2) = 2(2x-2) = 4x-4Answer = (B) 4x-4

4x-4 is correct answer of the given question.

2(x+b)=2(x+x-2)=4x-4

4x-4

b hai answer because the perimeter of rectangle is 2(l+b);given that the length is =x and breath is =x-2 solve = 2(x+x-2)=2(2x-2)=by multiply =4x-4 is answer

4×-4 is the perimeter of the rectangle

perimeter --2(l+b)2(x+x-2)=4x-4

your options b is correct 4x-4

4x-4 is the perimeter of the rectangle

2(l+b)2(x+x-2)2x+2x-44x-44x=4X=1

option b 4x-4 is right answer

(4x-4) is the answer because for finding perimeter do the sum of all sides

perimeter=2(l+b) =2(X+x-2) =4x-4

b is correct answer of this question

C 4x-2 is right for this question

2x-4 is correct answer

4x-4 is the best answere

Perimeter of rectangle =2(l+b)=2(x-2+x)=2x-4+2x=4x-4

06Expres 0,999,.. in the form p/q. Are you surprised why the answer makes sense

Answer»

Letx= 0.9999…There is only one repeating digit so multiply by 10 we get10x= 9.9999…x= 0.9999…subtract x now we get9x= 9Divide by 9 we getx= 9/9 = 1

divide 25 in to 2 parts such that 7 times the first part added to 5 time the second part makes 139

Answer»

This word problem related to linear

equations in one variable.

Given sum of two parts = 25

Let first part = x

second part should be = 25 - x

7 times the first part = 7x

5 times the second part = 5( x - 25 )

Given relation between to parts is

7 times the first part added to 5 times

the second part = 139

Now write the word problem into

Linear equation

7x + 5( 25 - x ) = 139

7x + 125 - 5x = 139

2x = 139 - 125

2x = 14

x = 14/ 2

x = 7

Therefore

First part = x = 7

Second part = 25 - x = 25 - 7 = 18

Answer»

Let the larger number = xThen the square of the smaller number = 8 times the larger number = 8xand the square of the larger numbe r = xAccording to the question,x - 8x = 180=> x - 8x - 180 = 0=> x - 18x + 10x - 180 = 0=> x(x - 18) + 10(x - 18) = 0=> (x - 18) (x + 10) = 0=> x - 18 = 0 or x + 10 = 0=> x = 18 or x = -10Thus, the larger number = 18 or -10Then, the square of the smaller number = 8(18) or 8(-10)= 144 or -80The square of a number can't be negative, so, the square of smaller number = 144Hence, the smaller number = sqrt(144) = 12The numbers are 12 and 18
