Question

Anyone know the answers to 10, 11, 12?

Answer 1

10. F.

11. A.

12. F.

Explanation:

10.

(5x + 6) + (-x + 8) = 5x - x + 6 + 8 = (5x - x) + (6 + 8) = 4x + 14

11.

We have w x blocks and 4 "unit" blocks, so it represents 4x + 4

12.

45xy = 9x*5y; 18x = 9x*2, also there is no GCF of 5y and 2, so answer F is correct.

G. 9y is not divisible by 9x

H. 19x is not divisible by 9x

J. x is not divisible by 9x
