Answer:
19
Step-by-step explanation:
2x+7=45
2x=45-7
2x=38
2x/2=38/2
X=19
Answer:
x = -5 or x = -12
Step-by-step explanation:
x^2+17x+72=12
Subtract 12 from both sides.
x^2+17x+72-12 = 12-12
x^2+17x+60=0
Then factor the left side of the equation
(x+5)(x+12) = 0
Then set the factors equal to 0
(x+5)=0 or (x+12)=0
Therefore x=-5 or -12
Answer:
x < 0
Step-by-step explanation:
0 > -3x -2x
0 > - 5x
dividing both side by -5
0 > x
or,
x < 0
