Good!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Ok so you can see 2 triangles that i highlighted, flip it so it is the same direction as you can see from the drawing
using the similar triangle equation
you get
136/64 = x/136
cross multiply and get
64x=18496
x=289
hope it help
Last one and first. You can find out why by isolating the cube root and cubing both sides.
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
