Answer:
Step-by-step explanation:
3n + 5d = 20.25
24n + 40d = 162
8n + 8d = 38
-24n - 24d = -114
24n + 40d = 162
-24n - 24d = -114
—————————
16d = 48
d = 3
A drive costs $3
3n + 5(3) = 20.25
n = 1.76
A notebook costs $1.75
Answer:

Step-by-step explanation:
Area of rectangle= Length*Width
so
multiply each coefficient of a times 4a^2
then take a^2 common factor so it will be
=area
36/48 = 6/8 = 3/4
reduced by 6 and then again by 2
Using the factor theorem, it is found that the polynomial is:

Given by the first option
---------------------------
Given a polynomial f(x), this polynomial has roots
using the factor theorem it can be written as:
, in which a is the leading coefficient.
---------------------------
In this question:



- By the options, leading coefficient

Thus:



Which is the polynomial.
