What do squares, rectangles, and right triangles have in common? They all contain at least one right angle!
What shape has at least one right angle?
rectangle
A rectangle is a four-sided shape where every angle is a right angle (90°). Also, the opposite sides are parallel and of equal length.
The answer is 8, that line is 180° and we know 140. 180-140=40 and it’s 5x so that leaves us with 5x=40. divide 5 on both sides leaving 8
F(x) = a(x - h)2 + k
f(x) = a(x + 2)2 - 7
(0,-3)
-3 = a(0 + 2)2 - 7
4 = a(2)2
4 = 4
1 = a
f(x) = 1(x + 2)2 - 7 = x2 + 4x - 3
