Find factored form of -7y-y^2=0

-y(y + 7) = 0

y = 0

y = -7

Step-by-step explanation:

-7y – y^2=0

y(-7-y) = 0

[y can be factored out because -7y and y² are both multiplied by y, -7y and -y² = -7(y) and -y(y). They have a common variable factor of y]

-y(7 + y) = 0

[-1 can also be factored out because -7 and -y both have a negative]

-y(7 + y) = 0 → -y = 0 and (7 + y) = 0.

-y = 0 → -y÷-1 = 0÷-1 → y = 0

(7 + y) = 0 → 7 + y – 7 = 0 – 7 → y = -7

answer: ouch. thats difficult

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
