Length = 2(width)
perimeter = 36 cm
using variables where x = width and y = length
Perimeter = 2x + 2y = 36 cm
y = 2x
solving for length 2x + 2(2x) = 36 cm
2x + 4x = 36 cm
6x = 36 cm
x = 6 cm
so y = 2(6 cm) = 12 cm
area of rectangle = 12 cm * 6 cm = 72 cm^2
The final equation is (x-5)^2 + (y+4)^2 = 10^2.
Hopefully this'll help you!
<span>draw out a triangle and then create three boxes inside by drawing a T. In each of the boxes you've created you need to put one of the letters from the equation. The equation you currently have is F= m*a. To rearrange this equation put the m and the a into the bottom boxes and the F above. Because there is a vertical line between the m and the a, this means you times them. If there is a horizonal line between two letters you divide them. So to find a, you must divide F by m. </span>
9pi/8 = 8pi/8 + pi/8 = pi + pi/8
12 + pi - 9pi/8 = 12 + pi - pi - pi/8
