There will be 42 in each row with 2 left over
Answer:
12
Step-by-step explanation:
The side of the square is (12x+52)/4=3x+13.
Answer:
10x^2 + 14x - 2
Step-by-step explanation:
So for the perimeter, you have to solve 2(7x-2) + 2(5x^2+1)
So distribute the 2s on both s we get 14x - 4 + 10x^2 + 2
This in standard form is 10x^2 + 14x - 2
