Answer:
2(x² - 2)(x² - 8)
Step-by-step explanation:
Given
2 - 20x² + 32 ← factor out 2 from each term
= 2( - 10x² + 32)
let u = x², then
- 10x² + 32 = u² - 10u + 32 = (u - 2)(u - 8)
change u back to x²
- 10x² + 32 = (x² - 2)(x² - 8) and
2 - 20x² + 32 = 2(x² - 2)(x² - 8) ← in factored form
Given the information, we have the following:
since the distance from each boundary of the tennis court to the fence is the same (x feet), then we have:
therefore, the expression that gives the are of the entire surface inside the fence is A=(36+2x)(78+2x)

Step-by-step explanation:
The n th term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio, hence
= 6 ×
= 6 × -
= 6 × -
= -
