Answer:
Molly paid for each song $1.5
Step-by-step explanation:
Let
x ------> amount that Molly paid for each song
we know that
The amount that Molly paid for each song multiplied by 8 is equal to the gift card value
so
The linear equation that represent this problem is

Solve for x
Divide by 8 both sides


Molly paid for each song $1.5
Answer:a and d
Step-by-step explanation:
i did it
Simple
like when you buy something at the store. the person is selling products to you
<span>a2 – b2 = (a + b)(a – b) or (a – b)(a + b).
This is the 'Difference of Squares' formula we can use to factor the expression.
In order to use the </span><span>'Difference of Squares' formula to factor a binomial, the binomial must contain two perfect squares that are separated by a subtraction symbol.
</span><span>x^2 - 4 fits this, because x^2 and 4 are both perfect squares, and they are separated by a subtraction symbol.
All you do here to factor, is take the square root of each term.
√x^2 = x
√4 = 2
Now that we have our square roots, x and 2, we substitute these numbers into the form (a + b)(a - b).
</span>
<span>(a + b)(a - b)
(x + 2)(x - 2)
Our answer is final </span><span>(x + 2)(x - 2), which can also be written as (x - 2)(x + 2), it doesn't make a difference which order you put it in.
Anyway, Hope this helps!!
Let me know if you need help understanding anything and I'll try to explain as best I can.</span>
