Answer:
h(x) = (x + 5)² − 18
Step-by-step explanation:
h(x) = 7 + 10x + x²
h(x) = x² + 10x + 7
Complete the square. (10/2)² = 25, so:
h(x) = x² + 10x + 25 − 18
h(x) = (x + 5)² − 18
Answer:
400 sq. ft.
Step-by-step explanation:
We gotta find the length of a side:
First, we divide 80 by 4, because the perimeter of a square is (4 x side):
80 ft. / 4 = 20 ft.
Second, we doing the normal area of a square equation:
= 400 square ft.
Which leads to out answer of 400 sq. ft.
A- 10.5
B- 5.25
is what the answers are
Translated down is changing y coordinate
(-2,4)
4-6 = -2
Coordinates of A’ is (-2,-2)
(-4,-7)
reflect over the y-axis
(x,y) -> (-x,y)
(-4,-7) -> (4,-7)
Coordinates of B’ is (4,-7)
Hope this helps!
