Answer:
D, -1
Step-by-step explanation:
when distributing the 2 to the 2x and 5 you get the same equation as the other side.
do paranthesis first, then exponent, then multiply, add then subtract from left to right
37.5
9/24=0.375
Move the decimal two places and you get 37.5%

Its answer b and write it 5x !!!!!!!!!!!!!!!!!!!
Answer:
The diagonal of the rectangle is approximately 42.5 inches.
Step-by-step explanation:
The area of a rectangle is given by the following formula:
area = width*length
In this case the width = 2*length, therefore we have:
area = 2*length²
722 = 2*length²
2*length² = 722
length² = 361
length = sqrt(361) = 19 inches
width = 2*length = 2*19 = 38 inches
The diagonal forms a right triangle with the sides of the rectangle, where it is the hypotenuse. Therefore we can use Pytagora's theorem:
diagonal = sqrt(length² + width²)
diagonal = sqrt(19² + 38²) = 42.485 inches
The diagonal of the rectangle is approximately 42.5 inches.
