Answer:
11.5
Step-by-step explanation:
We solve using :
Pythagoras Theorem
LM² = MN² + NL²
NL² = LM² - MN²
NL = √LM² - MN²
NL = √14² - 8²
NL = √(132)
NL = 11.489125293
NL = 11.5
Therefore, the length of NL = 11.5

Step-by-step explanation:
Answer:
2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms
= 3x² + (2x - 12x) + (- 8y + 7y)
= 3x² + (- 10x) + (- y)
= 3x² - 10x - y
