Y = 2x² + 30x + 200
y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)

Answer:
Step-by-step explanation:
When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use 
.
We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.
Say we have the equation 
. Our goal is to find the value of . <u>We can do this by getting x isolated on one side so we have something equal to x</u>.
We can subtract 5 from both sides and divide both sides by 5.
We now know the value of since it’s on one side of the equation.
Hope this helped!
A prime number can only be divided by one oritslef and a composite number can bedivided by other njmbers.
4 because it is the only number on the x side of the table that you can get a single value for y from
Answer:
So first converthem into a deciaml if the number line is ordered by decimals or make them from least to greatest, left to right.
Decimal:
If asking for s decimal, the -1 is definitely the least so -1. For -5/7, it’s just -0.71 (rounded), for 2/7, its 0.28 and for 6/7 its 0.86.
