Answer:
m<LMN = 167°
Step-by-step explanation:
Given:
m<LMT = 23°
m<TMN = 144°
Required:
m<LMN
SOLUTION:
m<LMN = m<LMT + m<TMN (angle addition postulate)
m<LMN = 23° + 144° (Substitution)
m<LMN = 167°
Step-by-step explanation:
- You would eliminate the terms with the y variables.
- You would use addition because you are trying to eliminate y to find the value of x.
Answer:
1a 2a
Step-by-step explanation:
n × (−2+5 ) = −8+20
n × 3 = 12
n = 4
2 + (n+6) = −1+6
n + 8 = 5
n = -3
The answer is 8...............
Answer:
After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
Step-by-step explanation:
We need to complete the square:
x^2 − 4x − 8 = 0
x^2 -2(x)(2)+(2)^2 -8 -4 =0
(x^2 -4x +4) - 12 = 0
(x-2)^2 -12 =0
Now, finding the value of x
(x-2)^2 -12 =0
(x-2)^2 = 12
taking square root on both sides

So, After completing the square the expression is (x-2)^2 -12 =0 and real solution are x = 5.46 and x = -1.46
