Elena went to the store where you can scoop your own popcorn and buy as much as you want.she brought 10 ounces of spicy popcorn

kifflom [539]

Answer:

A. 4 ounces

Step-by-step explanation:

Given that Elana paid $2.50 for 10 ounces of popcorn, let x be the amount popcorn a dollar will buy.

Thus we have:

$2.50 = 10 ounces

$1 = x

Cross multiply

$2.50 × x = 10 ounces × $1

Divide both sides by $2.50

($2.50 × x)/$2.50 = (10 ounces × $1)/$2.50

x = (10 ounces)/2.50

x = 4 ounces

Therefore, you can buy 4 ounces of popcorn per dollar

What is the correct factorization of x^2 - 2x - 15?

iragen [17]

Answer:

option b

Step-by-step explanation:

${x}^{2} - 2x - 15$

${x}^{2} - 5x + 3x - 15 = 0$

$x(x - 5) + 3(x - 5) = 0$

$(x - 5)(x + 3) = 0$

x = -3 (Not possible)

x = 5

So, x = 5

What is this equation, equivalent to c(x)=(x+6)^2+14

Digiron [165]

<h3>Answer: x^2+12x+50</h3>

Work Shown:

c(x) = (x+6)^2+14

c(x) = (x+6)(x+6)+14

c(x) = x(x+6)+6(x+6)+14

c(x) = x^2+6x+6x+36+14

c(x) = x^2+12x+50
