For this case we must factor the following expression:

We take the sign "-" as a common factor of the expression, taking into account that:

To factor, we must find two numbers that, when multiplied, result in -48 and when added, result in -2. These numbers are -8 and +6.

Then, we factor the expression within the parenthesis as:

Answer:

Each ounce of yogurt costs $0.12 so 8 ounces would be $0.96
Answer:
Step-by-step explanation:
perimeter of a square = 4 x length (L)
8x - 10 + 8x - 10 = 4L
rearrange the expression
8x + 8x - 10 - 10 = 4L
16x - 20 = 4L
divide both sides for L to stand alone
(16x - 20)/ 4 = 4L/4
(16x - 20)/4 = L
