Answer:
A=630 in^2
Step-by-step explanation:
Triangles: there are two equal triangles so we can treat them as one rectangle
A = 15 * 14 = 210
Rectangle:
A=30 * 14 = 420
A_total = 210 + 420 = 630 in^2
Answer:
I think it is
A.) AB is perpendicular to MN
Step-by-step explanation:
this is what would make sence for me
the frist one was confusing
In line two, Madlime added positive one in the bracket, but subtracted one outside of the bracket without considering the factor outside of the bracket. Therefore, line 2 should be f(x)=3(x2+2x+1-1)-7
Line 3: f(x)=3(x+1)2-7-3
Line 4: f(x)=3(x+1)2-10
The solution is -5/4= -1 1/4
