Answer:
x=2 or x=1 where x is integer.
Step-by-step explanation:
even numbers are the multiple of 2 or which are perfectly divided by 2 i.e. 2,4,6 etc.
Let 'x' be the first even number and 'x+2' be the second even number.
now translate the given sentence into mathematical order we write as.
x*(x+2)=5x-2
now simplify for x we get the integer.
x*x+2x=5x-2
=5x-2x-2
=3x-2
-3x+2=0
since above eqn is quadratic i.e. having greater power is 2, so using quadratic formula or middle term braking or completing square we get the value of x or integer.
using middle term braking we get the values of integers.
-2x-1x+2=0
x(x-2)-1(x-2)=0
(x-2)(x-1)=0
x-2=0 and x-1=0
x=2 or x=1

2*4=10-2
8=8
<h3>
Answer: C. 12 pouches for $2.80</h3>
Explanation:
x = number of pouches
y = cost for having x number of pouches
To find the unit cost, divide y over x
For choices A through D we have the following unit costs
- y/x = 2.04/8 = 0.255
- y/x = 2.69/10 = 0.269
- y/x = 2.80/12 = 0.233 (approximately)
- y/x = 3.80/16 = 0.2375
We see that 0.233 is the lowest unit cost, so therefore, Choice C is the lowest cost per pouch.
