Answer:
1 and 19
Step-by-step explanation:
I believe this is a factoring problem.
Example:
If we have the equation x^2-2x-3
We can find two numbers that multiply to -3 that add to -2
The two numbers are -3 and 1
(x-3)(x+1)= So x=3 and x=1

Answer:
T₁₀
Step-by-step explanation:
We know the first term is 21, which is a
We work out the difference by taking 21 away from 42 which equals 21.
We then use the general formula:
Tₓ = a + (x-1)(d)
We need to find the term which equals 210
210 = 21 + (x - 1)(21)
210 = 21 - 21 + 21x
210 = 21x
x = 10
Hence it is the 10 term when the thing equals 210.
Answer:
x
Step-by-step explanation:
The center of the circle is in the middle of the circle
X is the center of the circle
There are 2 ways to do this...
19,500(1.06) = 20,670
or
19,500 + 0.06(19,500) = 19,500 + 1170 = 20670
