The perimeter of a rectangle is 64 inches. The width of the rectangle is 5x inches. Find the
length in terms of x.

Step-by-step explanation:

Perimeter, p = 64 inches = 2 (l + w)

width, w = 5x inches

length = l

slot in the value of w in 64 = 2 (l + w)

64 = 2 (l + 5x)

expand

64 = 2l + 10x

64 - 10x = 2l

divide both sides by 2

64 - 10x / 2 = l

length =

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
