OB. 10x4 + x + x2 + 4x
O C. 7x6 – x2 - y2 + 4x
O D. 7x + 6x4 - x - x2 + 4x

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*

3/6 chance

step-by-step explanation:
