Answer:
A) length = width +10
B) length * width = 144 OR
B) width = 144 /length putting B) into A)
A) length = 144 / length + 10 then solving for length
A) length^2 = 144 +10 length
A) length^2 -10 length - 144 = 0 then we factor
(length -18) * (length +8) = 0
length = 18 feet
width = 8 feet

Answer:
Negative infinity
Step-by-step explanation:
The line points down infinitely in the graph.
-1/4*x^2-x+3=-1/4*(x^2+4x)+3=-1/4*(x^2+4x+4)+4=-1/4*(x+2)^2+4
x0=-2
