Answer: x = 6
Step-by-step explanation:
Each trianglar side has an area: (1/2)*8*9=36
the base is a square with an area of 8*8=64
so the total surface area is 36+36+36+36+64=208
Take the root of both sides, and solve.
x = 2i sqrt 2, -2i sqrt 2.
Answer: -5 and 2
Because it equals 3 when added.
And -10 when multiplied.
