Answer:
-a^2 -a -35
Step-by-step explanation:
a(4-a) -5(a+7)
Distribute
4a -a^2 -5a-35
Combine like terms
-a^2+4a -5a-35
-a^2 -a -35
The difference (subtraction) of 6 times a number (x represents number) and 7. This gives us 6x-7. That is equal to five times (multiplication) the sum (addition) of the number, x, and 4. This gives you = 5(x+4) and combined gives us B, 6x-7=5(x+4).
Step-by-step explanation:
F -------> 1/d²
12 -------> 1/3²
12 ×(3/6)² ----->1/6²
3----->1/6²
