None.... Have you mistyped anything?
Anyway you just have to substitute the values inside brackets in the expression to find its value.

If: g(x) = 13x - 5, then g(-2) = 13(-2) - 5

What is the area of a regular hexagon with a distance from its center to a vertex of 1 cm? (Hint: A regular hexagon can be divid

devlian [24]

<h3>Answer:</h3><h3>Exact area = $\frac{3}{2}\sqrt{3}$ square cm</h3><h3>Approximate area = 2.598 square cm</h3>

=================================================

Work Shown:

s = side length of equilateral triangle = 1 cm

A = area of equilateral triangle with side length 's'

$A = \frac{\sqrt{3}}{4}*s^2$

$A = \frac{\sqrt{3}}{4}*1^2$

$A = \frac{\sqrt{3}}{4}$

This is just one of the 6 equilateral triangles (see diagram below)

Multiply by 6 to get the area of all 6 equilateral triangles, or the entire hexagonal area

$6*A = 6*\frac{\sqrt{3}}{4}$

$6A = \frac{3\sqrt{3}}{2}$

$6A \approx 2.598$

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = x + 3

g(x) = -x + 2

(f + g)(x) is f(x) + g(x)

Substitute in function values: (f + g)(x) = x + 3 - x + 2
[Subtraction] Combine like terms (x): (f + g)(x) = 3 + 2
Add: (f + g)(x) = 5
