First you would multiply the 4cds by the cost of each cd, so, 4X14.99=59.96
Answer:

Step-by-step explanation:

Answer:
The value of c is 36
Step-by-step explanation:
Now, we fine the perfect square polynomial, we need to have the expression of the form:

so this can be written as a perfect square as: 
Now the expression given to us is:

so when c is 36, we will get:

Now, this can be re-written as:

so here we can see that it is of the form:

so the perfect square is:

Hence, when c = 36 we get a perfect square.
Answer: Commutative property of addition
The order doesn't matter when it comes to adding.
The general rule can be written as x+y = y+x.
Answer:
E
Step-by-step explanation:
You have to get t^2 in the first equation.
x = t^3 Take the cube root of both sides
![\sqrt[3]{x} = \sqrt[3]{t^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%20%3D%20%5Csqrt%5B3%5D%7Bt%5E3%7D)
Now square both sides

Now you can substitute into the second equation
y = t^2 - 2
y =
- 2
E
