Answer:
10 months
$500
Step-by-step explanation:
Option 1
- 300 + 20x, where x is the number of months
Option 2
Both options reveal same amount:
- 300 + 20x = 100 + 40x
- 300 - 100 = 40x - 20x
- 200 = 20x
- x = 200/20
- x= 10 months
Cost of notebook:
- 300 + 20*10 = 300 + 200 = $500
Answer:

Given data in the question:-
Dividend=
Divisor=
Solution:-
To find the remainder using the remainder theorem. We have to substitute -2 in the dividend and on solving that we will get the remainder.
We got -2 from the divisor when we equate the divisor to 0.
x+2=0
x=-2

Substituting -2 in above written equation.

Step-by-step explanation:
<u><em>Definition of: Coefficient</em></u>
A number used to multiply a variable.
<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
Variables with no number have a coefficient of 1.
<u><em>Example</em></u>: x is really 1x.
<em><u>coefficients:</u></em>
3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>
<u><em>sum of the coefficients:</em></u>
3 + 5 + 1
8 + 1
