Answer:

$this \: paper \: needs \: to \: be \: folded \: \\ \underline{ \boxed{twice \: (2 \: times)}}$

Step-by-step explanation:

$let \: the \: let \: the \: length \: be \to \: x \\when \: folded : it \: becomes \to \: \frac{x}{2} \\hence : \to \\ 93.5 \times \frac{x}{2} = (93.5 - 1) \\ 93.5x = 2(93.5 - 1) \\ 93.5x = 2 \times 92.5 \\ 93.5x = 185 \\ x = \frac{185}{93.5} \\ \boxed{x = 1.9786096257 }\\$

Q(a+1) - 2q(a) if q(x) = x²+3x+4

siniylev [52]

$q(x) = {x}^{2} + 3x + 4$

_________________________________

Step(1)

To find q(a) we just need to put a instead of x in q(x) function.

Let's do it...

$q(a) = {a}^{2} + 3a + 4$

Multiply sides by -2 :

$- 2q(a) = - 2( {a}^{2} + 3a + 4)$

$- 2q(a) = - 2 {a}^{2} - 6a - 8$

_________________________________

Step (2)

To find q(a+1) we just need to put a+1 instead of x in q(x) function.

Let's do it...

$q(a + 1) = ({a + 1})^{2} + 3(a + 1) + 4 \\$

$q(a + 1) = {a}^{2} + 2a + 1 + 3a + 3 + 4 \\$

$q(a + 1) = {a}^{2} + 5a + 8$

_________________________________

Step (3)

$q(a + 1) - 2q(a) =$

${a}^{2} + 5a + 8 - 2 {a}^{2} - 6a - 8 = \\$

$- {a}^{2} - a = - a(a + 1)$

And we're done.

Thanks for watching buddy good luck.
