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
verification
2*4=10-2
8=8
In number form it sounds like it would be 600,201,094

Hello there.
Step-by-step explanation
I literraly dont know this, I'm doing this for the points, sorry >:(
Answer: y^2 - 6y - 2. To find the sum, add the like-variables. You add them because there is a plus between the two sets of parenthesis. Take away the parenthesis (since there aren’t any factors taken out of either one) and add or subtract accordingly. Since 5y^2 and -4y^2 have the same variable AND exponent, they can be added. The same goes for the -9y and 3y. After adding the like-variables, you should get y^2 - 6y - 2.
