Answer:

Step-by-step explanation:

if you divide all of them by 7x, you get

x^3 - 2x^2 - 4

There are no other factors.

The first two have a factor of x, but the last one doesn't

the last two have a factor of 2, but the first one doesn't

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.

Im broke have this but like whats 24X58-9=<br><br><br><br> 800x24=?

Mekhanik [1.2K]

Answer:

24X58-9=1,383

800x24=19,200

Step-by-step explanation:

24x58=(24x8)+(24x50)

24x8=160+32=192

24x50=200+1,000=1,200

192+1,200=1,392-9=1,383

800x24=3,200+16,000=19,200

John had 5/8 of a pizza left after a party. He gave 3/8 of a pizza to his friends to take home and kept the rest.

lorasvet [3.4K]

I'm assuming your trying to find how much pizza he has left.

You need to subtract the two fractions because the denominators are already the same.

When subtracting fractions, you leave the denominator and regularly subtract the numerator.

Your answer will be 2/8 which equals 1/4th
