X^2+4x=-3
x^2+4x+3=0
(x+1)(x+3)=0
x+1=0 so x=-1
x+3=0 so x=-3
so the solution is x=-3,-1

The lines with a slope of 0 are horizontal lines because all the points on the line have the same y-coordinate on a graph. Using the slope formula on the line will give you 0.
The slope is equivalent to the rise over run. Since the
slope of the bike ramp is ¼, the rise is equivalent to 1 and the run is
equivalent to 4. To get the angle of the bike ramp make with the ground, let us
use the equation tanθ= rise/run.
Therefore, tanθ= ¼.
Θ=tan-1 (1/4)
So the angle of the bike ramp is Θ= 14degrees

Answer:
7
Step-by-step explanation:
Count the units (Squares) from the first point to the second and you will see that it is 7 units away.
