i think this is correct but i'm not completely sure
Answer:
Multiply both sides by 2
Subtract l from both sides
Divide each side by 3
(2R -l)/3 =w
Step-by-step explanation:
R = (l+3w)/2
Multiply both sides by 2
2R = 2* (l+3w)
2R = l+3w
Subtract l from both sides
2R - l = l-l +3w
2R -l = 3w
Divide each side by 3
(2R-l) /3 = 3w/3
(2R -l)/3 =w
We keep the 2x^2 because we can only subtract something from that if it also is squared. From there, we subtract the 7x from 2x^2-11. Since there is no previous x's in the 2x^2-11, we just make it -7x. So, without even continuing the problem, we see that A) is the correct answer because it is the only one with -7x.
