The ratio of girls to boys would be 16:12 because if you divide 28 by 2 you get 14. subtract 2 to on one of them and add the two to the other. You get 12 and 16. There is a difference of 4 to them and when you add them together you get 28. :)
If there aren’t any degrees and it doesn’t state that the triangle is equilateral then you cannot solve this equation without more information

If you're trying to solve for 0:
<- Subtracted 18 from both sides
<- Divided both sides by 60 and then simplified.

<- Decimal Form
Give Brainliest for simple answer plz :P
Answer:
c = 64
Step-by-step explanation:
Given
x² - 16x + c
To complete the square
add ( half the coefficient of the x- term )² to x² - 16x
x² + 2(- 8)x + 64
= (x - 8)²
Thus
x² - 16x + 64 = (x - 8)² ← a perfect square
with c = 64
