Answer:
170 ft^2
Step-by-step explanation:
The surface area of a square prism is 2 times the base area + 4 times the area of a lateral face.
S=2(25)+4(30)
S=50+120
S=170
You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
Step-by-step explanation:
If f(x) =x, is the father function, then all it's child function would be equally inclined to x and y-axis respectively.
