Answer:
254 yds²
Step-by-step explanation:
There are 6 faces of the prism we need to calculate the area of for a rectangular prism.
The base and top of the prism measure 9x7 yards each, so there are two faces with an area of 63 yds² (9 x 7 = 63)
The sides of the prism measure 4x7 yards each, so there are two faces with an area of 28 yds² (4 x 7 = 28)
The front and back face of the prism measure 9x4 yards each, so there are two faces with an area of 36 yds² (9 x 4 = 36)
The total surface area is
2(63) + 2(28) + 2(36) = 254 yds²
Answer:

No
Step-by-step explanation:
u and o arent elements of {a, b, c, d, e, f, g, h, i}
Answer:
in 13.95 years the senior class will have 100 students.
Step-by-step explanation:
P(h) = p(0.92)^t (equation for exponential change)
P(h) - population of highschool (or senior class) = 100
p - staring amount = 320
t = time in years
100 = 320(0.92)^t
1/3.2 = .92^t (divide both sides by 320)
log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)
13.9497 = t
To simplify, you must distribute the 2 into the 5x and -4 by multiplying 2 with 5x and 2 with -4.
<span>2(5x – 4) + 3x
2 x 5x = 10x
2 x -4 = -8
You will get 10x - 8 + 3x
Now you must combine like terms or add like terms. In this case we must add 10x and 3x
10x + 3x = 13x
Finally the answer would be 13x - 8</span>
