Let C(x) be the function which calculates the total cost of making x skirts.
There is going to be a fixed constant, 250, to which we will add 15$ per x skirts.
So C(x)=250+15x
Answer: 250+15x
5^(x+3)=25^(x-2)
Apply the exponent rule ( 5 ^2 = 25, so remove the 5 and replace 25?with 2)
x + 3 = 2(x-2)
Simplify:
X + 3 = 2x -4
Add 4 to both sides:
X + 7 = 2x
Subtract x from both sides
X = 7
Answer: x = 7
Answer:

There are 10 boys and 1 of them is a sophomore
The volume of a pyramid is equal to 1/3 multiplied by the base of the pyramid multiplied again by the height. In this case, the base of the pyramid is a square. Hence the area should be s^2. The volume now becomes V = 1/3 * s^2 * h = 1/3 * s^2 * 9 = 48. length,s is not equal to 4. Answer is A. 4 inches.
