Answer:
9.38cm
Step-by-step explanation:
you have a right triangle. use pathagorean
x^2 + 9^2 = 13^2
x^2 + 81 = 169
x = √88
x = 9.38
The true regarding the functions on the graph is f(2) = g(2)
<h3>How to determine the true statement?</h3>
The graph that completes the question is added as an attachment
From the attached graph, we can see that both lines intersect at:
x = 2
This means that:
f(2) = g(2)
Hence, the true regarding the functions on the graph is f(2) = g(2)

The correct answer is: [A]: " 4x³ + x² + x + 3 " .
______________________________________________________
Explanation:
______________________________________________________
(3x³ + 2x² + 2x + 1) + (x³ − x² −<span> x + 2) =
</span>↔ (x³ − x² − x + 2) + (3x³ + 2x² + 2x + 1) =
<span>
</span>(x³ − x² − x + 2) + (3x³ + 2x² + 2x + 1) =
x³ − x² − x + 2 + 3x³ + 2x² + 2x + 1 ;
<span>
Combine the "like terms" ;
x</span>³ + 3x³ = + 4x³ ;
−x² + 2x² = + x² ;
− x + 2x = + x ;
+ 2 + 1 = + 3 ;
_____________________________________________________
And rewrite:
_____________________________________________________
→ " 4x³ + x² + x + 3 " ;
→ which is: "Answer choice: [A]: " 4x³ + x² + x + 3 " .

A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). To find the area of a regular polygon, you use an apothem — a segment that joins the polygon's center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).
