The answer is 3p+6 gggghhnbhjjn
They are all perfect squares
(9x+2)(9x+20
(9x+2)^2
Answer:
60°
Step-by-step explanation:
2x and x are linear pair,
=> 2x + x = 180
=> 3x = 180
=> x = 180/3
=> x = 60°
=>2x =120°
-9×+1=-×+17
-9×=-×+16 (subtract 1 from both sides)
-8×=16 ( add x to both sides)
×=-2 (divide -8 from both sides)
5/2 = 2.5
you can check by multiplying 2.5 and 2.
