A rectangle has a length of 4x plus 5 and a width of 8x minus 4. Which expression shows the perimeter of that rectangle? A: 4x +

mezya [45]

Answer: The answer is (D) $24x+2.$

Step-by-step explanation: Given that there is a rectangle, where length of the rectangle is given by

$\ell=4x+5,$

and width of the rectangle is given by

$b=8x-4.$

We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.

Therefore, perimeter is given by

$p=2\ell+2b=2\times(4x+5)+2\times(8x-1)=8x+10+16x-8=24x+2.$

Thus, the correct option is (D).

Two angles are supplementary. if the larger angle is 3 degrees more than twice the smaller angle then how big is each angle. wri

Margaret [11]

Two angles are supplementary when they add up to 180 degrees.

x = smaller angle
2x+3 = larger angle

x + 2x + 3 = 180
3x = 180 - 3
3x = 177
x = 177/3
x = 59° ← smaller angle

2x + 3 = 2*59 + 3 = 121° ← larger angle
