Step-by-step explanation:
4(2x-1)+3(2x+5)
8x-4+6x+15
8x+6x-4+15
14x+11
The solution to x + 8.5 = 64.5 is 56.
x + 8.5 = 64.5
- 8.5 - 8.5
---------------------------
x = 56
It is B, 100 percent sure
Answer:
13. 14. 15.
A.) 21 A.)-2 A.) 8
B.) 21 B.) 14 B.) 8
Step-by-step explanation:
13.
A.) 2(4)^2 - 11 = 21. B.) 2(-4)^2 - 11 = 21
* Note: if the power is a even number (2, 4, 6, and on), then the negative won't affect the answer and can be forgotten.
