Answer:
7/12
Step-by-step explanation:
Find the common denominator 24 so fraction would change to 6/24 + 8/24
that equals 14/24 and simplified that 7/12
Fern's estimate is not correct because he rounded 548 wrong, it would be rounded to 550 instead since the number 8 is closer to 10. So the correct answer would be 420.

Answer:
ab^3x - 8b^3x
Step-by-step explanation:
(a - 8)b^3x
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
