Answer:
7x³ + 13x²+ 8x +9
Step-by-step explanation:
(3x² + 2x + 7x³) + (10x² + 6x + 9)
= 3x² + 2x + 7x³ + 10x² + 6x + 9
= 7x³ + (3x²+ 10x²)+ (2x+ 6x) +9
= 7x³ + 13x²+ 8x +9
2: yes
The answer is C: P=8h
For every hour worked he is making $8. For example, if he worked 6 hours he would make 48 dollars.
a. F = ma
F/a = ma/a
m = F/a
b. F = ma
-30 = -6a
a = 5
c. F = ma
30 = 10a
a = 3
