- 3x + 2 ( - 6x² + 13x - 6 )
= - 3x - 12x² + 26x - 12
= - 12x² + 23x - 12
Answer:
LM = 16
Step-by-step explanation:
From the question given:
L is the midpoint of NM
NL = 3x + 1
LM = 8x - 24
LM =?
Next, we shall determine the value of x.
This can be obtained as follow:
Since L is the midpoint of NM, it means that NL and LM are equal i.e
NL = LM
Thus, we can obtain the value of x as follow:
NL = 3x + 1
LM = 8x - 24
NL = LM
3x + 1 = 8x - 24
Collect like terms
3x - 8x = - 24 - 1
-5x = - 25
Divide both side by - 5
x = -25/-5
x = 5
Finally, we shall determine the length of LM as follow:
LM = 8x - 24
x = 5
LM = 8(5) - 24
LM = 40 - 24
LM = 16
Therefore, the length of LM is 16

Step-by-step explanation:
Answer:
x =10
Step-by-step explanation:
angles are equivalent
170 = 2x + 6x + 90
170 - 90 = 8x +90 - 90
80 = 8x
10 = x
