There are 20 squares total you shaded 5
Answer:
10. ( 7x + 2 ) × ( 5x + 1 )
Step-by-step explanation:
1. 35x² + 10x + 7x + 2
2. 5x × ( 7x + 2 ) + 7x + 2
3. ( 7x + 2 ) × ( 5x + 1 )
Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.
This means 5x + 8x = 13x and -7 - 55 = -62
The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.
The second option square root of 2^5
