Your answer is-6
Answer:
the answer is 5
Step-by-step explanation:
L = 2 + .5W
2L + 2W = 40
SOLVING (if needed)
Substitute 2 + .5w in for l in the second equation and solve for w.
2(2 + .5w) + 2w = 40
4 + w + 2w = 40
Combine like terms and subtract 4 from both sides
3w = 36
Divide both sides by 3
w = 12 in.
l = 2 + .5w
l = 2 + .5(12)
l = 8 in.
(6f-5+3g)-(-6g+3) = <span>6f-5+3g-(-6g)-3) = 6f-8+3g+6g = 6f+9g-8.</span>
