Answer:
Step-by-step explanation:
(6,18)
<span>(f+g)(x) = f(x) +g(x)
= (7x^3 −2x−12) +(−3x^3 -8x^2 +10x</span>)
= x^3(7 -3) +x^2(-8) +x(-2+10) +(-12)
= 4x^3 -8x^2 +8x -12
Corresponds to selection C.
Answer:
The answer is 3,240
Step-by-step explanation:
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.
In mathematics, the interior angles of a polygon are the angles on the inside of the polygon created where the sides of the polygon meet. When a polygon is a n-sided regular polygon, meaning it has n sides, its sides have the same length, and its angles have the same measure, we have that the measure of one interior angle is given by the formula
Answer:
6.11
Step-by-step explanation:
First Step:
8a + 6.80 = 55.68
Second Step:
Subtract 6.80 from 8a and 55.68
8a = 48.88
Third Step:
Divide 8 from 48.88
a = 6.11
Answer:
N = 3
Step-by-step explanation:
I don't know what the whole thing above is, but just disregard that.
All it is here is cross multiplication.
So 28N = 21 * 4
Multiply...
28N = 84
And divide each side by 28
N = 3
