Answer:
Step-by-step explanation:
First, let's get anything with a 
to one side by itself, so this means we need to subtract 
from both sides:
Finally, let's divide 
from both sides to get by itself on one side:
9+9+2=20
9+8+3=20
9+7+4=20
9+6+5=20
(These ones are kin of repeated but in a different order:)
9+5+6=20
9+4+7=20
9+3+8=20
9+2+9=20
Answer:
pentagon is a 5 sided polygon with interior angles that add to 540 degrees. Regular pentagons have sides of equal length and interior angles of 108 degrees. The US Department of Defense headquarters is named 'the Pentagon' . ... A hexagon is a 6 sided polygon with interior angles that add to 720 degrees.

Answer:
f(x) = (1/2)(x-2)^2(x+1)(x+2)
Step-by-step explanation:
You can determine this by looking at the zeroes of the graph. For any zero that goes through the x-axis, the power of that zero is odd. For any zero that that "bounces" from the x-axis, the power of that zero is even.
Starting from left to right, we can see that the first zero, -2, goes through the x-axis. That means (x+2) is raised to an odd power. The second zero, -1, also goes through, so (x+1) is raised to an odd power. The last zero, 2, bounces off the x-axis, so (x-2) is raised to an even power. The only functions that satisfy this criteria are function 1 and 2.
However, we are not done yet. We need to figure out which multiplier value (1/2, 1/4) is correct. To do this, we plug in 0 for x, since we know that the y-intercept is 4. When we plug in 0, we see that f(0) = 4 for the first function. Therefore, the first function is the answer.
