Answer:
See below in bold.
Step-by-step explanation:
(x - 1)(x^2 + 1)
= x(x^2 + 1) - 1(x^2 + 1)
= x^3 + x - x^2 - 1
= x^3 - x^2 - x - 1.
Leading coefficient = 1.
Constant term = -1.
Degree = 3. (because of the x^3).
<h2>
The total number of items does he buy 5 (three pens and two notebooks).</h2>
Step-by-step explanation:
The total amount spend by Mr. Loretta = $4.83
The cost of each pen = $0.95 and
The cost of each notebook = $0.99 and
To find, total number of items he buy = ?
∴ The cost of one pen and one notebook = $0.95 + $0.99 = $1.94
The cost of two pens and two notebooks = $1.94 × 2 = $3.88
∴ The cost of three pens and two notebooks = $3.88 + $0.95 = $4.83
Thus, the total number of items does he buy 5 (three pens and two notebooks).
Answer:
ez
Step-by-step explanation:
For a all you have to do is multiply by 3 so the answer would be -15
For b all you have to do is subtract 12 then divide by -1 so the answer would be -0.5
for c all you have to do is divide by -10 so the answer would be -0.1/-10 or 0.1/10
Answer:
x^2 +2x +1
Step-by-step explanation:
(x+1)^2
=(x+1)(x+1)
= x×x+x×1+1×x+1×1
=x^2+x+x+1
=x^2+2x+1
