I'm pretty sure it's D because you're subtracting 30 without changing it.
Answer:
i dont know if this is the answer u want
4+(7*8)=x
x= 60
Step-by-step explanation:
If you do 1040-400 you get 640
then you need to divide that by 4 to get 160 leaving you with the width, to get the length you have to add 200 to the width meaning the length is 360
length = 360
width = 160
She forgot to distribute the 2 fully.
ie. After the 3 to the 9x.
It should have been,
2(3 + 9x) - 2x
6 + 18x - 2x
6 + 16x
