Yo sup??
a.For this part just draw a triangle with sides 4,8 and 8 inches respectively.
The sides having 8 inches should make equal angle with the base side.
b.One angle is 20
The other two angles be x and y
but x=y because its an isosceles triangle
x+y+20=180
2x=160
x=80
Hope this helps.
I think you just divide the 130 ft by the 40 ft = 3.25 ??
Hello from MrBillDoesMath!
Answer:

Discussion:
From the table, the local minimum of -15 occurs when x = -2 and x = 2 BUT the answers provided do not include x = -2. The only remaining answer is
(2, -15)
Thank you,
MrB
Take 10x +55x first making 66x
then you'll have 66x^2 +25 for you simplified answer
