The formula you need to use is a^2 + b^2 = c^2. A is the side of 3 and B is the side of 7, so 3^2 + 7^2 = c^2.
9 + 49 = c^2
58 = c^2
√58 = C
So your answer is C. √58. I hope this helps!
Answer:
-8(x+2.5)^2
This is the same function as if you were to graph h(g(f(x)))

Answer:
110 ft
Step-by-step explanation:
The length of fencing is four times the perimeter of one garden.
The formula for the perimeter of a rectangle is
P = 2l + 2w
The total perimeter for all four rectangles is
P = 4× (2l + 2w) = 8l + 8w
Data:
l = 9¼ ft
w = 4½ ft
Calculation:
P = 8l + 8w = 8×9¼ + 8×4½ = 72⁸/₄ + 32⁸/₂ =(72 + 2) + (32 + 4) = 74 + 36 = 110 ft
The total length of fencing is 110 ft.
