360=2w+2l
l=8+w
Substitute for l
360=2w+2(8+w)
360=2w+16+2w
360=4w+16
344=4w
86=w
Plug in the w value
l=8+(86)
l=94
Final answer: Length-94 inches, Width-86 inches
Jessica’s mistake is that when isolating h from b, she multiplied b instead of dividing it on both sides. The new formula for h would be A/2b=h.
Now let’s solve. 23/2(6)=h
23/12
Approx. 1.91

Answer:
- see the attachment for a graph
- domain: all real numbers
- range: -6 and y>-5
Step-by-step explanation:
The graph below was created by a graphing utility.
It shows no horizontal gaps: f(x) is defined for all values of x, so the domain is all real numbers.
It shows a vertical gap between y=-6 and y>-5. So, the range is in two parts:
{-6} ∪ {y > -5}
(-9)•(-9)•(-9)•(-9)= 6,561
