L = 4w
2L + 2W ≤ 130 cm
I would use the substitution method for this one.
Answer = 2(4w) + 2w ≤ 130 cm
For ever 40 hours jeff works he makes $560 that was simple
for every hour he works he makes $14
Answer: 4). A = (b1 + b2)h/2
5).
A = (b x h)/2
6). A = b x h
7). A = b x h = 65 x 50 = 3250 ft^2
8). A = (b x h)/2 = (12 x 18)/2 = 108 inches^2
9). A = (b1 + b2)h/2 = (15 + 7)4/2 = 44m^2
