how about you stop being confused
Step-by-step explanation:
just read the question
2/10 represents 20 percent, as 10 is 100% because it is the Max, so something like 4/10 would be considered 40%
A) w + 7 = L
B) w * L = 120
A) w = L -7 then substituting this into B)
(L-7) * L = 120
L² -7L = 120
L² -7L -120 = 0
Solving by quadratic Formula:
L1 = 15
L2 = -8
If length = 15, then width = 8
