Which of the following represents the area of a rectangle whose length is 3x + 5 and whose width is x - 2? (1 point)

Answer:
A = 3x² - x - 10
Step-by-step explanation:
the area (A) of a rectangle is calculated as
A = length × width , then
A = (3x + 5)(x - 2)
each term in the second factor is multiplied by each term in the first factor.
A = 3x(x - 2) + 5(x - 2) ← distribute parenthesis
= 3x² - 6x + 5x - 10 ← collect like terms
= 3x² - x - 10
Answer:
<em>A = 3x² - x - 10</em>
Step-by-step explanation:
<em>A = length × width</em>
<em>A = (3x + 5)(x - 2)</em>
<em>A = 3x(x - 2) + 5(x - 2) </em>
<em>A = 3x² - 6x + 5x - 10 </em>
<em>A = 3x² - x - 10</em>
