Arectangle has an area of 864 square centimeters and a length of 24 centimeters. what is the width of the rectangle?
a: 18 cm
b: 24 cm
c: 28 cm
d: 36 cm

The answer is D. 36, simply divide 864 by 24

Area of a rectangle is
A= l*w
l - length
w-width

substituting the values given to you
864 = 24 *w

solving for width
dividing 24 to both sides

864/24 = 24/24 *w
24/24=1
864/24=w

i dont carry a calculator around, but thats how you solve the problem

Answer: 24x^3√(5x) - 4x^3√(10x)mark me brainliest

What am i doing here. add?
