Hello there!
-3| 2x + 6| = -12
2x + 6 = -12/-3
2x + 6 = 4
Solve absolute value
We know that 2x + 6 = 4 or 2x + 6 = -4
We have two possibilities to solve this.
1)
2x + 6 = 4
2x = 4 - 6
2x = -2
Divide both sides by -2
2x/-2 = -2/-2
x = 1
2) 2x + 6 = -4
2x = -4 - 6
2x = -10
Divide both sides by 2
2x/2 = -10/2
x = -5
Answer : X = -1 or X = -5
A+ Guaranteed!
Answer:
Step-by-step explanation:
<u>Given the sequence </u>
<u>We see it is an AP with</u>
- The first term a = 13
- Common difference d = 13 ( as 26 - 13 = 39 - 26 = 13)
<u>The 12th term is:</u>
- a₁₂ = a + 11d = 13 + 11*13 = 156
Answer:
6x+90+11x+5=180(sum of interior angle of triangle)
17x=180-95
x=85/17=5 is your answer
-15 <u><</u><u>-</u><u>1</u><u>9</u>
- When we come to case of negative numbers we go right the opposite of positive integers.
- The less number is greater and greater is less
- hence -15 is greater than -19.
