Answer:

n = 975

Step-by-step explanation:

$a_1 = 5 = 5 \times 1\\a_2 = 10 = 5 \times 2\\\\Therefore, \ a_n = 5 \times n\\$

$Given \ a_n = 4875\\\\So, a_n = 5 \times n \\\\=> 4875 = 5 \times n\\\\=>\frac{4875}{5} = n\\\\=> 975 = n$

Find x and identify the measurement of

spin [16.1K]

Step-by-step explanation:

90+x+8+3x+2 = 180(linear pair)

or, 100+4x=180

or, 4x = 80

so, x = 20

<BOC = x+8+3x+2

= 20+8+3×20+2

= 90

so, <BOC = 90

Factor the trinomial completely. <br> 2x^4 -20x^2+ 32

sveticcg [70]

Answer:

2(x² - 2)(x² - 8)

Step-by-step explanation:

Given

2 $x^{4}$ - 20x² + 32 ← factor out 2 from each term

= 2( $x^{4}$ - 10x² + 32)

let u = x², then

$x^{4}$ - 10x² + 32 = u² - 10u + 32 = (u - 2)(u - 8)

change u back to x²

$x^{4}$ - 10x² + 32 = (x² - 2)(x² - 8) and

2 $x^{4}$ - 20x² + 32 = 2(x² - 2)(x² - 8) ← in factored form
