Use the remainder theorem to divide 5x^2+9x-2 by x+3. What is the remainder

marishachu [46]

Answer:

Step-by-step explanation:

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

f(-3) = 5(-3)^2 +9(-3) -2

=5(9) - 27 -2

= 45-29

= 16 !

svet-max [94.6K]

The percentage of reduction is 17%

<u>Explanation:</u>

Original price = $21

Reduced price = $17.43

Percentage of reduction = ?

Difference in price = $21 - $17.43

= $3.57

Percentage of reduction = $\frac{difference}{original} X 100$

$= \frac{3.57}{21} X 100\\\\= 17$

Therefore, percentage of reduction is 17%
