Answer:
a = 3
Step-by-step explanation:
Factor both expressions
x² - x - 6
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)
The factors are - 3 and + 2 , since
- 3 × 2 = - 6 and - 3 + 2 = - 1 , thus
x² - x - 6 = (x - 3)(x + 2)
-----------------------------------
x² + 3x - 18
consider factors of constant term (- 18) which sum to give the coefficient of the x- term (+ 3)
The factors are + 6 and - 3 , since
6 × - 3 = - 18 and 6 - 3 = + 3 , thus
x² + 3x - 18 = (x + 6)(x - 3)
Both expressions have a common factor of (x - 3)
Compare with (x - a ), then a = 3
Hey there!
12 ≥ 5f - 18
5f - 18 ≤ 12
ADD 18 to BOTH SIDES
5f - 18 + 18 ≤ 12 + 18
SIMPLIFY IT!
5f ≤ 30
DIVIDE 5 to BOTH SIDES
5f/5 ≤ 30/5
SIMPLIFY IT!
f ≤ 6
Therefore, your answer is: f ≤ 6
Good luck on your assignment & enjoy your day!
