Answer:

(s+t)(x) = s(x) + t(x)

(s*t)(x) = 2x³ + 4x²

Step-by-step explanation:

(s+t)(x) = s(x) + t(x)

= x + 2 + 2x²

= 2x² + x + 2

(s*t)(x) = s(x) * t(x)

= (x + 2) * 2x²

= 2x³ + 4x²

Answer:

x = 0 or x = -2

Step-by-step explanation:

x^4+8x=0

Step 1: Factor left side of equation.

x(x+2)(x2−2x+4)=0

Step 2: Set factors equal to 0.

x=0 or x+2=0 or x2−2x+4=0

x=0 or x=−2

If Ruby plans on making 4 batches of pancakes, how many combined cups of powdered milk and whole wheat flour does she need?

Trava [24]

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.

Given the quantities of powdered milk and whole wheat to prepare a batch of pancakes, we can determined the total amount of each ingredient by simple rule of three:

Powdered milk

$x = 4\,batches\times \frac{1}{4}\,\frac{cups}{batch}$

$x = 1\,cup$

Whole wheat

$y = 4\,batches \times \frac{3}{2}\,\frac{cup}{batch}$

$y = 6\,cups$

Ruby needs a cup of powdered milk and six cups of whole wheat to prepare four batches of pancakes.
