Which of the following shows the division problem below in synthetic division form? 4x^2-13x+8 / x+5

Tju [1.3M]

Answer:

Dividing 4x^2 - 13x + 8 by x + 5 or x - (-5), in synthetic division form:

-5) 4 | -13 | 8

↓ 4 x (-5) (-5) x (-33)

4 -33 173

=> Quotient is 4x - 33 and remainder is 173

=> (4x^2 - 13x + 8)/(x + 5) = (4x - 33) + 173/(x + 5)

Hope this helps!

Each year lizzy e's school purchases students agenda books, which are sold in the school store.This year, the school purchased 3

notsponge [240]

In order to make back the money they spent ($1,137.50) plus $1500, they want to make $1137.5+1500=2637.5$ $2,637.50 total.

They want to make this amount by selling 350 agendas, so divide the amount they want to make by 350 to find the amount per book:
$2637.5/350=7.54$
I rounded the answer to the nearest hundredth because the hundredth is the smallest amount we have in USD (the penny.)
So they need to charge at least $7.54 to make back their money plus $1500.

Hope I helped, and let me know if you have any questions :)

Twice the sum of a number and 3 is equal to three times the difference of the number and 3

lana66690 [7]

Twice the sum of a number and 3 = 2(n + 3)
three times the difference of the number and 3 = 3(n - 3)
so
Twice the sum of a number and 3 is equal to three times the difference of the number and 3:
2(n + 3) = 3(n - 3)
2n + 6 = 3n - 9
n = 15

answer
2(n + 3) = 3(n - 3)
n = 15
