Answer: 30x⁴
Step-by-step explanation:
2x⁴ + (-3x²)² + 10(x²)² + (-3x²)²
2x⁴ + (9x⁴) + 10 (x⁴) + (9x⁴)
2x⁴ + 9x⁴ + 10x⁴ + 9x⁴
2x⁴ + 10x⁴ 9x⁴ + 9x⁴
12x⁴ + 18x⁴
30x⁴
(-x)² = x²
(xᵃ)ᵇ = xᵃᵇ

Answer:
The number of subscribers in 2008 is 110,845,988
Step-by-step explanation:
The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.

And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.

So

Find the number of subscribers in 2008.
2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).

The number of subscribers in 2008 is 110,845,988
