Answer:
The length of the container is ![14\ in](https://tex.z-dn.net/?f=14%5C%20in)
Step-by-step explanation:
we know that
The surface area of a triangular prism (a mailing container) is equal to
![SA=2B+PL](https://tex.z-dn.net/?f=SA%3D2B%2BPL)
where
B is the area of the triangular base
P is the perimeter of the triangular base
L is the length of the container
step 1
Find the area of the base B
![B=\frac{1}{2}(2)(1.7)=1.7\ in^{2}](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B1%7D%7B2%7D%282%29%281.7%29%3D1.7%5C%20in%5E%7B2%7D)
step 2
Find the perimeter of the base P
![P=3(2)=6\ in](https://tex.z-dn.net/?f=P%3D3%282%29%3D6%5C%20in)
step 3
Find the length L of the container
we have
![SA=87.4\ in^{2}](https://tex.z-dn.net/?f=SA%3D87.4%5C%20in%5E%7B2%7D)
![B=1.7\ in^{2}](https://tex.z-dn.net/?f=B%3D1.7%5C%20in%5E%7B2%7D)
![P=6\ in](https://tex.z-dn.net/?f=P%3D6%5C%20in)
substitute and solve for L
![87.4=2(1.7)+(6)L](https://tex.z-dn.net/?f=87.4%3D2%281.7%29%2B%286%29L)
![L=[87.4-2(1.7)]/(6)](https://tex.z-dn.net/?f=L%3D%5B87.4-2%281.7%29%5D%2F%286%29)
![L=14\ in](https://tex.z-dn.net/?f=L%3D14%5C%20in)

Answer:
C. 24
Step-by-step explanation:
by algebra:
let "?" be x
35/30 = 28 / x (multiply both sides by 30)
35 = (28/x) (30) (multiply both sides by x)
35x = (28)(30)
35x = 840 (divide both sides by 35)
x = 840 / 35
x = 24
