first one. Since its X crosses or passes (2,0)
Step-by-step explanation:
Answer:
The mean is 20
Step-by-step explanation:
17+19+21+23=80
80 div 4 = 20
6 * 2.5 = 15 That’s the area of the base
2.5 * 4 = 10
10 * 2 = 20
That’s the area of the 2 smaller sides
6 * 4 = 24
24 * 2 = 48
That’s the area of the 2 larger sides
Then you add all the dimensions together.
15+20+48 = 83.
So, the final equation is (6*2.5) + 2(2.5*4) + 2(6*4) = 83
Answer:
below
Step-by-step explanation:
area to be repaired = 24*15=360ft^2
1 bag = 2ft^2
? 360ft^2
360/2 = 180 bags needed
cost of bags = 180*24.95=4491$
Answer:
63 m
Step-by-step explanation:
Perimeter is 276, 2L + 2W = 276, so L + W = 138
L = 75
138 - 75 = W
63 m
