That would be 1^2 + 20 , 2^2 + 20 and 3^2 + 20 (replacing n by 1 , 2 and 3)
= 21, 24 and 29 Answer
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

Hope this helps. Sorry if the expression is in the wrong form.
Answer:
x < −6 or x ≥ 3
Step-by-step explanation:
Whenever they are split apart, we will be using "or". Second, you see how the left side of the number line is graphed? All x-values go up to -6 with an open circle, therefore it is <em>less</em><em> </em><em>than</em><em>,</em><em> </em>NOT <em>less</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em>[circle NOT closed]. The right side of the number line, however, does have a closed circle starting from 3, therefore it is <em>greater</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em><em>,</em><em> </em>NOT <em>greater</em><em> </em><em>than</em><em> </em>[circle NOT open].
