the 4.89 for 1 gallon is cheaper because it saves you money
Step by step:
3n-18=4n+18
~subtract 3n from both sides:
-18= n + 18
~subtract 18 on both sides
answer: -36=n
Answer:
y = (x+4)^2 -19
Step-by-step explanation:
y = x^2 + 8x + 16 – 3 – 16
You are almost done with completing the square
y = (x^2 + 8x + 16) – 19
= (x+4)^2 -19
This is in vertex form y= a(x-h)^2 +k where (h,k) is the vertex
4/7 can be equivalent to 8/14 (Multiplied top and bottom of fraction by 2)
It can also be equivalent to 12/21. (Multiplied by 3)
16/28.
And so on.
Two angles can be complementary angles add up to 90. So if you have a angle that is 30 and another one that is 60 those would be complementary because if you add them up they add up to 90.
