Answer:

Let x represents the number.

Given the statement: "Three less than the product of a number and two, increased by five".

"Product" means multiply

"Product of a number and two" translated to 2x

"Three less than the product of a number and two" translated to 2x - 3

Increased by 5 means +5

then;

the  given statement becomes;

(2x-3)+5

Therefore, the expression that represents "three less than the product of a number and two, increased by five" is (2x-3)+5

Distributive Property

<u>Algebra I</u>

  • Terms/Coefficients
  • Expanding (FOIL)

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = 1 - x²

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function f(x)]:                                                                          f(2x + 4) = 1 - (2x + 4)²
  2. Expand [FOIL]:                                                                                                  f(2x + 4) = 1 - (4x² + 16x + 16)
  3. (Parenthesis) Distribute negative:                                                                   f(2x + 4) = 1 - 4x² - 16x - 16
  4. Combine like terms:                                                                                          f(2x + 4) = -4x² -16x - 15
