Answer:
C. 12x² + 8x + 25
Step-by-step explanation:
A. 12x² + 15
B. 20x² + 25
C. 12x² + 8x + 25
D. 24x² + 16x + 50
Hypotenuse = 8x²
Height = 4x² + 15
Base = 8x + 10
Perimeter of the triangle = hypotenuse + height + base
= 8x² + (4x² + 15) + (8x + 10)
= 8x² + 4x² + 15 + 8x + 10
Perimeter of the triangle = 12x² + 8x + 25
C. 12x² + 8x + 25
Answer:
It's actually -4/5 if you are multiplying -2 times 2/5
-1/5 out of a fraction= -0.2
-4/5 out a fraction= -0.8
Step-by-step explanation:

Answer:
A. 179 sq. ft.
Step-by-step explanation:
Area of walkway + fountain: (3.14)11^2=379.94 ft^2
Area of fountain: (3.14)8^2=200.96 ft^2
Area of walkway : 379.94-200.96=178.98 ft^2 which is also rounded to 179ft^2
