<em>We will assume the tent is in the shape of a triangular prism.</em>
The volume of a triangular prism can be found with the following formula, where  is the width at the base,
 is the width at the base,  is the height, and
 is the height, and  is the length.
 is the length.

Substitute in the known values.

Simplify — use multiplication.



Simplify — use division.

Answer:
64x+56 & 24x+56
Step-by-step explanation:
I hope this is what you mean because this is not an equation as it is not set equal to anything.
Both problems solved by distributive property - 
8*8x + (8*7) = 64x+56
8*3x + (8*7) = 24x+56
 
        
             
        
        
        
Answer:
y=14
Step-by-step explanation:
Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent. 
 
 
plug in 25 in 2x and you would get 50°
Since the sum of a triangle is 180° you could set up an equation 
Then, add 50+50=100+10=110
then you would then have 
subtract 110 from 180, leaving you with 70

then divide and you would get 14
Check:
5(14)+10+50+50= 180
