8x + 9 - 6x + 2
Simplify
8x+ 9 - 6x + 2: 2x + 11
= 2x + 11 <----- your answer
Please tell me if this was right
Answer:
X=14
Step-by-step explanation:
17^2+b^2=19^2
289+b^2=361
361-289=72
The square root pf 72 is ~8.5
subtract 17 from 31 (to get rid of the triangle bases on the bottom).
31-17=14
X=14
