If X is the variable, then X/(-12+9) = x/(-3) = -X/3
x + 12 = -12
This cannot be answered. You will have to find the value to the letter X.
Converting the word problem to an equation: X = 12(2(sqrt(36)) Evaluating for X: X = 12(2(6)) X = 12(12) X = 144
X^2 + 24x + 144 = 0. Dontcha just luv algebra? You are looking for a polynomial: (X+somenumber) * (X+somenumber) = X^2 + 24x + 144. Then just solve for (X+somenumber) * (X+somenumber) = 0. The trick is to find the pair of factors of 144 that add up to 24. These are the pairs of factors of 144: 1 x 144 2 x 72 3 x 48 4 x 36 6 x 24 8 x 18 12 x 12 You want the pair of factors that add up to 24: 1 + 144 = more than 144 and is too large 2 + 72 = more than 72 and is too large 3 + 48 = more than 48 and is too large 4 + 36 = more than 36 and is too large 6 + 24 = 30 8 + 18 = 26 12 + 12 = 24! so, (X +12) * (x + 12) = X^2 + 24 +144 = 0 So either (X +12) or the other (X +12) is going to be zero because you can only get zero from multiplying something by 0. If X+12 =0, then put -12 on both sides of the equation: X+12 -12 = 0 -12 x + 12-12 = -12 x + 0 = -12 x = -12. Normally you would then solve for the other (X+12) = 0, but that's the same thing as what we just did. So this time, there is only one answer x = -12.
x+12
To write "12 more than x," you would express it as x + 12. This means you are adding 12 to the variable x. In mathematical terms, the phrase "more than" implies addition. So, x + 12 represents the value that is 12 greater than x.
It is simply: x+12
15(x+12)
12 is more than 1.2 by 10.8. 1.2 x 10 is also 12.
If X is the variable, then X/(-12+9) = x/(-3) = -X/3
9+(x/4)=12 x/4=3 x=12
Let the unknown number be x and so the expression is: x+12
X is greater than or equal to 12
2n+12=x
let X = number quotient = x/4 x/4 + 9 = 12 x/4 = 3 x = 12
x + 12 = -12
