Answer:
c = 7
Step-by-step explanation:
6c = 7c - 7
Subtract 6c to both sides
0 = c - 7
Add 7 to both sides
c = 7
Answer:
x ≤ - 4
Step-by-step explanation:
Given
3 - x ≥ 2x + 15 ( add x to both sides )
3 ≥ 3x + 15 ( subtract 15 from both sides )
- 12 ≥ 3x ( divide both sides by 3 )
- 4 ≥ x, hence
x ≤ - 4
Option B) (x + 3)^2 − 5 is the correct answer
Step-by-step explanation:
Given expression is:
We will solve eah expression in the options to chek which is equivalent to given expression
So,
<u>A) (x + 3)^2 + 5</u>
NOT equivalent
<u>B) (x + 3)^2 − 5</u>
Equivalent
Hence,
Option B) (x + 3)^2 − 5 is the correct answer
