First get n's by them selves
-6 = 10n -4n (remember to always change sign when crossing the equals sign.
-6 = 6n ( subtract and take sign of the larger) ( then divide both sides by 6 to solve for n)
-1 = n
hope this helps
<span>A=1/2(a+b)h for h.
First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h
You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.
2A = (a + b)h
Now divide both sides by (a+b).
2A/(a+b) = h
Should be 1,188 , because 1,188 divided by six would be 198, hope I could help
Answer:
C
Step-by-step explanation:
Given
f(x) = x² + x + 1
To obtain the function in vertex form use the method of completing the square.
Add/ subtract ( half the coefficient of the x- term )² to x² + x
f(x) = x² + 2( )x + - + 1
= (x + )² + → C
You could try using a box-and-whisker plot. Those are really good for these types of questions
