Answer:
-2(r+3)
Step-by-step explanation:
If x=3
Just replace the X with 3
So seven minus three equals four
If 3 is X than do 4 times 3 which that makes twelve.
Five-5
three-3
"the quantity five plus three" (5 + 3)
"one hundred times the quantity ..." means 100 (5 + 3)
now just solve 100(5+3)
solve the parentheses first (5+3) = 8
Now you are left with 100(8) or 100*8
when you solve your answer is 800
