Answer:
The coefficient is 
Step-by-step explanation:
The given sum is

We can choose to add only the coeffients of
or simplify the whole sum.

We collect the LCM for the
terms;

This will give us;

Which is the same as

The coefficient is 
X1 = -12 , x2 = 8 ... is the answer
Answer:
Both of the equations are right because if you take s=4p, then reverse it, p=1/4 of s because 4 of p is equal to s so s/4 = p
Answer:
260 = d + 236 or d + 236 = 260
Step-by-step explanation:
Mental Math
Each increases by a certain amount called the common difference
4.4-2.8=1.6
6-4.4=1.6
7.7-6=1.7
hmm, some error
maybe you meant 7.6
common difference is 1.6
answer is C
