Answer:
u=8
Step-by-step explanation:
You solve the parenthesis first . Then you multiply it by 10 . Then you add that and answer to 2x . So in total you would get 22x or 22x^2
Answer:
x = 17
Step-by-step explanation:
Since the triangles are similar then corresponding angles are congruent.
∠ I = ∠P ← substitute values and solve for x
3x + 4 = 72 - x ( add x to both sides )
4x + 4 = 72 ( subtract 4 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
