Answer:
√180 or 5√6
Step-by-step explanation:
Plug in: a^+b^2=c^2
a^2+12^2=18^2
a^2+144=324
subtract 144 from both sides
a=√180
a= 5√6
To identify the real number that corresponds to a point plotted on the real number line, locate the point on the number line and determine which number it represents.
To identify the real number that corresponds to a point plotted on the real number line, you need to locate the point on the number line and determine which number it represents. Each point on the number line corresponds to a unique real number.
For example, let's say a point is plotted on the number line between -5 and -4. This point would correspond to the real number -4.5 because it is exactly halfway between -5 and -4.
Using this method, you can determine the real number for any point plotted on the real number line.

x^2+6x+4= -2x+4
Answer:
0,-8
Answer explanation:
x^2+6x+4=-2x+4
or, x^2+6x+4+2x-4=0
or, x^2+8x=0
Therefore, x(x+8)=0
Either,
x=0
or,
x+8=0
x=-8
hence,x=0, -8
