I'm not quite sure what this question means, but d = rt is a formula used to calculate the distance. the variables here are d for distance, r for rate, and t for time. if you need to solve it for t:
d = rt ... divide both sides by the rate (r)
(d/r) = t ... is your result
Answer:
X^2 + 11x + 30
Step-by-step explanation:
x*x= x^2
x*6= 6x
x*5= 5x
6*5= 30
x^2 +6x+5x+30
Combine like terms
x^2 + 11x + 30
Answer:
C) x ≥ 11 or x ≤ -3
Explanation:
Given following: |x − 4| ≥ 7
Apply absolute rule: If |u| ≥ 0 then u ≤ -a, u ≥ a
Solving stepwise:
⇒ x - 4 ≤ -7, x - 4 ≥ 7
<u>change sides</u>
⇒ x ≤ -7 + 4, x ≥ 7 + 4
<u>add/subtract integers</u>
⇒ x ≤ -3, x ≥ 11
