Answer:

6 and 8

Step-by-step explanation:

Let's start off by thinking at what the question is asking us.

The product (multiplication) of two even numbers (x)(x+2) is which means =,

12 more (12) than the square of the smaller number (x).

So put that all together and you get (x)(x+2)=12+x^2=

Distribute the x, (x)(x+2)=

x^2+2x=x^2+12 Subtract x^2 from both sides.

2x=12

Divide both sides by 2 and you get x=6

So the two numbers are 6,8

6(8)=12+6^2

48=48

Jack and Jill both ordered pizzas from Wayne's Pizza for their parties. Jack paid $58.50 for 3 pepperoni pizzas and 2 plain pizz
just olya [345]

Answer:

A plain pizza is $10.50 and a pepperoni pizza is $12.50

Step-by-step explanation:

Create a system of equations where x is the price of a pepperoni pizza and y is the price of a plain pizza:

3x + 2y = 58.5

2x + 4y = 67

Solve by elimination by multiplying the top equation by -2:

-6x - 4y = -117

2x + 4y = 67

Add these together and solve for x:

-4x = -50

x = 12.5

So, a pepperoni pizza is $12.50. Plug in 12.5 as x into one of the equations, and solve for y:

2x + 4y = 67

2(12.5) + 4y = 67

25 + 4y = 67

4y = 42

y = 10.5

So, a plain pizza is $10.50.

A plain pizza is $10.50 and a pepperoni pizza is $12.50
