Answer:
9 x 9 x 9 x 9 x 9
Step-by-step explanation:
9^5 = 9 x 9 x 9 x 9 x 9
Answer:
x ∈ R (all reals)
Step-by-step explanation:
14 - (2x + 5) = -2x + 9
Take out parentheses
14 - 2x - 5 = -2x + 9
Simplify
9 = 9
<em>Since 9 does equal 9, it means that this equation can be true for all real values of x.</em>
Answer:
-2
Step-by-step explanation:
rise over run = 4/-2 = -2
It's 72
the measure of exterior angle of any regular polygon = 360/number of sides = 360/5 = 72°
Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150
