Answer:
(x + 7)(x - 7)
Step-by-step explanation:
We need to factor [ x² - 49 ]
The middle number is 0 and the last number is -49.
Factoring is when we fill in the blanks for [ (x + _)(x + _) ]
We need to know what goes in the blanks, we need to know:
- two numbers that add to get 0
- two number that multiplied together get -49
We can try 7 and -7.
7 + (-7) = 0
7 * (-7) = -49
This works, so fill in the blanks for the factor.
(x + 7)(x + (-7))
(x + 7)(x - 7)
Best of Luck!
Since a serving is 1/2 cup and he needs 72 servings you can multiply 72 by 1/2 and find out that he needs to make 36 cups of punch. Two cups is a pint so he needs (36 / 2) 18 pints of juice. He already has the 8 pints of pineapple juice so 18 - 8 leaves 10 pints of orange juice.
Step-by-step explanation:
First we need to set up an equation so
12.50=4x+2.50
Simplify each side by subtracting the initial fee of 2.50
10=4x
divide by 4 to isolate x
2.5=x
