Sketch the graph of the following equations: y=x+5, y=-(x+5), and y = |x+5|

The surface area (sa) of a cube with a as the length of each of its sides is given by the formula . if the surface area is known, how can you rewrite the formula to find its side?

Don't know how to find x given these segment lengths

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'
