Answer:
x = - 7, x = 0
Step-by-step explanation:
Given
x² + 7x = 0 ← factor out x from each term on the left side
x(x + 7) = 0
Equate each factor to zero and solve for x
x = 0
x + 7 = 0 ⇒ x = - 7
Its 13, because you multiply -8 and the negative beside it which turns it into a positive so you add 8 and 5

Answer:
So we have 3 pounds of apples. 3 pounds= 6 dollars. This means for 1 pound, it costs 2 dollars. So since 1 pound is 2 dollars, take 10 pounds and multiply it by 2, you get 20 dollars. So the cost of 10 pounds is 20 dollars. If you wanna do it the short way, the cost is always twice the amount of the pounds.
