Answer:
33
Step-by-step explanation:
g(x) = 2x² + 1
g(-4) = 2(-4)² + 1
= 2(16) + 1
= 33
5 pages are colored pages in every 20 pages
The answer for 13 would be 4x-6x=2x
Answer:

Step-by-step explanation:
we are given different angles
we can see that each angles have different denominators
so, firstly we will find common denominators
denominators are 1 , 2,3,4,6
so, LCD will be 12
now, we will make denominator of all terms 12








we can see that denominators are same
so, we can arrange it according to numerators as

we can replace values
and we get order as

No, it would only work with similar terms. However, you would be able to multiply them, like 2x times 2y = 4xy.
