The value of X would be -2
The equation to find the value for all X values is X+22=Y
So, because Y is 20 we plug that information into the equation
Our new equation is now X+22=20
Now we solve for X
X+22=20
-22 -22
In the end it leaves us with X=-2
Hope this helps!
This is simple simplification
f(x) = 1/-6
If you want to form a square of 7500 soldiers, the side of the square must be
soliders.
But since you cannot have 0.6 solider, the general needs to find the closest perfect square to the number 7500 which is less than 7500.
That number is 7396 which when square rooted gives 86 soliders on the side.
Subtract 7396 from 7500 and get how many soliders were left out,

Hope this helps :)
f(-3) would be 36.
When looking at synthetic division, the numbers across the top represent the coefficients of x^2, x and the constant in that order. Therefore, the equation is as follows.
2x^2 - 5x + 3
Now we can put -3 into the equation and solve.
2(-3)^2 - 5(-3) + 3
2(9) + 15 + 3
18 + 15 + 3
36
