Answer:

23

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

g(x) = x² - 4

f(x) = -2x - 3

g(-6) is x = -6 for function g(x)

f(-6) is x = -6 for function f(x)

<u>Step 2: Evaluate</u>

g(-6)

  1. Substitute in <em>x</em>:                    g(-6) = (-6)² - 4
  2. Exponents:                          g(-6) = 36 - 4
  3. Subtract:                              g(-6) = 32

f(-6)

  1. Substitute in <em>x</em>:                    f(-6) = -2(-6) - 3
  2. Multiply:                               f(-6) = 12 - 3
  3. Subtract:                              f(-6) = 9

g(-6) - f(-6)

  1. Substitute:                    32 - 9
  2. Subtract:                       23

If the volume of the rectangular prism is represented by 6x2 – 2x + 8 and the base area is 2x – 4, which expression represents t
Harlamova29_29 [7]

\bf \textit{volume of a rectangular prism}\\\\ V=Lwh~~ \begin{cases} L=length\\ w=width\\ h=height\\ \cline{1-1} V=6x^2-2x+8\\ \stackrel{base}{Lw}=2x-4 \end{cases}\implies 6x^2-2x+8=(2x-4)h \\\\\\ \cfrac{6x^2-2x+8}{2x-4}=h\implies \cfrac{\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(3x^2-x+4)}{\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(x-2)}=h\implies \cfrac{3x^2-x+4}{x-2}=h
