Answer:
2x-1
Step-by-step explanation:
(10x-5)-(8x+6)
10x-8x-5+6
2x-1
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.
We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3
B and C are absurd; if a series converges, it must have a sum, but if a series diverges, it cannot have a sum.
Now, notice that

That is, we can write the sum more compactly as

The series is geometric with common ratio

, so the series converges (and thereby has a sum), so the answer is D.
Answer:
6c+10f
Step-by-step explanation:
Cost of 1 cheese pizza=6
Cost of c cheese pizza=6c
Cost of 1 four-topping pizzas=10
Cost of 1 four-topping pizzas=10f
Total cost=6c+10f
