Answer:

x  = ±2sqrt(2)

Step-by-step explanation:

x^2 = 8

Take the square root of each side

sqrt(x^2) = ±sqrt(8)

x = ±sqrt(4*2)

We know that sqrt(ab) = sqrt(a)sqrt(b)

x = ±sqrt(4)sqrt(2)

x  = ±2sqrt(2)

A movie theater decreased the size of its popcorn bags by 20%. If the old bags held 15 cups of popcorn, how much do the new bags
vovikov84 [41]

Answer:

<em>Your answer will be </em>12<em> cups of popcorn.</em>

Step-by-step explanation:

To find out how much the new bags hold, you need to find out the discount.

\frac{20}{100 } = .2

15 * .2 = 3

<em>We know that the discount is </em>3<em>.</em>

<em>To figure out how much the new bags hold, subtract by the old bags.</em>

15 - 3 = 12

<em>The new bags hold 12 cups of popcorn. </em>
