Set up a ratio:

12/5x-2 = 16/6x

Cross multiply:

12(6x) = 16(5x-2)

Use distributive property:

72x = 80x - 32

Subtract 80x from both sides:

-8x = - 32

Divide both sides by -8:

X = 4

Rachel buys 1 gallon of milk. Her sister Abby uses 1 1 2 quarts of the milk in a recipe. Then her mother uses 3 cups of the milk

mrs_skeptik [129]

1 Gallon is equal to 4 Quarts.

$4-1\frac{1}{2} =2\frac{1}{2}$

$2\frac{1}{2}$ Quarts is equal to 10 Cups.

$10-3=7$

There are 7 Cups left.

7 Cups is equal to 56 Fluid Ounces.

x to the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

snow_tiger [21]

Answer:

(x + 6)(x + 8)

Step-by-step explanation:

Consider the factors of the constant term (48 ) which sum to give the coefficient of the x- term (14 )

The factors are + 6 and + 8

since 6 × 8 = 48 and 6 + 8 = 14

x² + 14x + 48 = (x + 6)(x + 8) ← in factored form
