So in order to solve this we are going to cross multiply:
a 4
--- = --
15 5 so what were are going to do is we will take a and multiply it with 5 and we will take 15 and multiply it with 4. Now this gives us 5a and 60 so our new equation is:
5a = 60 now we are going to get our variable alone by dividing it by 5 and what we do on one side of the equation we do on the other:
5a = 60
÷5 ÷5 this gives us a=12
hope this answer helps

Step-by-step explanation:
Move decimal points 6 units to the right
To solve the problem you must apply the corresponding formulas for calculate the area of each figure. Therefore, you have:
1-A cube where the length of each edge is 4 inches: <span>96 square inches
</span><span> A=6a^2=96 inches^2
2- A triangular prism where the area of each base is about 20 square inches, the length of each side of the base is 6 inches, and the height of the prism is 2 inches: </span><span>76 square inches.</span><span>
3- A square pyramid with a base length and slant height of 5 inches: 75</span><span> square inches.
</span><span>A=2(5)(5)+5^2=75 inches^2
4- A rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches:</span>94 square inches .
A=2(4x5+3x5+3x4)=94 inches^2
