Answer:
Step-by-step explanation:
y = -3(x-3)^2 + 4
1.22
Calculate a rooms edge
28
AB + BC = AC
14 + 3x-4 = 4x+4
Combine like terms
10 +3x = 4x+4
Subtract 3x from each side
10+3x-3x = 4x+4-3x
10 = x+4
Subtract 4 from each side
10-4 =x-4+4
6 =x
We want AC
AC = 4x+4 = 4*6+4 = 24+4 = 28
2x + 5 - x simplified would be...
x + 5
