Answer:
86
Step-by-step explanation:
32×4=128
128-42=86
Answer:
2c^2 + 4
Step-by-step explanation:
2c^2 + 4 + 9 - 9 <- simplify
4 + 9 = 13, 13 - 9 = 4
2c^2 + 4
Hope this helps :)
(The ^ shows that it's an exponent)
T = 126.
13 = t/9 - 1 multiply both sides by 9
117 = t - 9 move terms
-t = -9 - 117
-t = -126 change the signs
t = 126
Answer:
26 units
Step-by-step explanation:

Using the formula above,
distance between (-10, 3) and (0, 27)




= 26 units
Answer:
B) 176 ft²
Step-by-step explanation:
The picture below is the attachment for the complete question. The figure has 3 halves of a circle and a square . The area of the figure is the sum of their area.
Area of a square
area = L²
where
L = length
L = 9 ft
area = 9²
area = 81 ft²
Area of the 3 semi circles
area of a single semi circle = πr²/2
For 3 semi circle = πr²/2 + πr²/2 + πr²/2 or 3 (πr²/2)
r = 9/2 = 4.5
area of a single semi circle = (3.14 × 4.5²)/2
area of a single semi circle = (3.14 × 20.25
) /2
area of a single semi circle = 63.585
/2
area of a single semi circle = 31.7925
Area for 3 semi circles = 31.7925 × 3 = 95.3775 ft²
Area of the composite figure = 95.3775 ft² + 81 ft² = 176.3775 ft
Area of the composite figure ≈ 176 ft²
