Is there any option to choose from ?
If so show them and I’ll probably be able to answer .
From what I know its 56.52m
80 + 60 + y = 180 and if y and x are vertical angles y = x
Answer:
(x - 4)² - 11
Step-by-step explanation:
Given
x² - 8x + 5
To obtain the required form use the method of completing the square.
add/subtract ( half the coefficient of the x- term)² to x² - 8x
= x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11
