write as an equation: the sides of a rectangle are x and (x – 4). the perimeter is 87.
a. 87 = 2x + 2(x - 4)
b. 87 = 2x + 2x - 4
c. 87 = x + (x - 4)
d. 87 + 2x = 2(x – 4)

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
