Use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute
2x•5x = 10x^2
2x•3= 6x
10x^2+6x
7•5x = 35x
7•3= 21
35x+21
2. combine like terms
10x^2+6x+35x+21
10x^+ 41x +21 [final answer]
Make the problem r=8-16. Then you will have r=-8, your answer
The answer is b, > because 30.17 is bigger than 30.018
9>n>17
it means that n can be whatever number between 9 and 17
