The answer would be m^2+3m+2=0 because the first “part” of the equation (x^2-5) is equal to m; in the equation it’s squared so it can be replaced by m^2. next, 3m is the same as 3(x^2+5) which is what you have when you see 3x^2+15. finally, you have to bring the -2 over from the other side so you have positive 2. hope this helps!
-2 or 2 is the answer. The absolute value of 2 is 2 and the absolute value of -2 is 2 because absolute value can not be negative.
Answer:
x = -7
Step-by-step explanation:
The whole line is 12
the whole line is also x + 14 and x + 12
so make them equal:
x+14 + x +12 = 12
2x + 26 = 12 now subtract 26 from both sides
2x = - 14 now divide both sides by 2
x = -7
False because you can subtract your way out of the set of whole numbers
