Answer:
1386
Step-by-step explanation:
If you have trouble with that, you can multiply 66 by 20, then 66*1, and add them (break apart the 21.)
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]
