The value of X is D. 25
Every triangle adds up to 180 degrees so you just add up the given numbers, then subtract that number from 180 and that is your answer.
1.)combine like terms: 12-2x=10x 3-10=-7
10x-7
Okay ShallBeTheLast, what we will do will involve a lot of simple plug and play kind of actions.
To start we must notice one number must be negative and the other should be positive, because the multiplied number is a negative.
Next, lets multiply number that have a sum of 10 (keep in mind one has to be negative and the other has to be positive).
-1 * 10 = -10 false
-2 * 12 = -24 false
-3 * 13 = -39 false
notice that no number working and it's only getting farther away.
There is no solution for this that involves to integers.
I think you might of wrote the question backwards.
If that is the case we would run numbers like.....
-1 * (-6) = 7 false
-2 * (-5) = 10 true!!!!
-2 and -5 would work
No the inequality symbol only changed when you divide a negative number from both sides.
