Answer:
-q
Step-by-step explanation:
We know that we are trying to find an expression equivelant to p - q:
p - q can be p - 1q
We can then put parenthesis around -1q:
p + (-1q)
We then can simplify:
p + (-q)
Answer:
pretty sure its a
Step-by-step explanation:
I do not have a explanation sorry bro
Answer:
12
Step-by-step explanation:


When F = 18; d = 2


Cross multiply;
18 x 4 = K
72 = K
There the equation connecting F and
is

Now, Find F when d = 6
All you do is to substitute d = 6 in to 

Therefore;
F = 12
Please mark me brainiest if correct.
Observe that as the series progresses, the term decreases by 1/4. To show this, observe the first four terms of the series below.
-200 = (1/4)(-800)
-50 = (1/4)(-200)
-12.5 = (1/4)(-50)
Since we have a common ratio, r, of 1/4, we can use the properties of a geometric series to find the 8th term of the series.
Recall that to find the sum of the nth term of a geometric series, we have

where a is the first term of the series and r is the ratio.
So, for the first eight terms, we have


Therefore, the sum of the 8th series is approximately -1066.65.
Answer: -1066.65
