For you to do area it is length times width.
X - (-20) = 5
When you subtract a negative, change it to addition:
X + 20 = 5
Subtract 20 from both sides:
X = -15
To calculate minimum value, do -b/2a to get the x-value, and plug it in to get the y-value:
-6/8 = -3/4

So the minimum value of g(x) is -81/4
This shows that g(x) has a lesser minimum value than f(x)
Answer:
UMAMI I think may be the answer to your question
Answer:
sln
b3=8(dived by 3 both sides)
b=8/3
I hope this help you
