Answer:
- 2 + 5x² - 2x + 4
Step-by-step explanation:
A polynomial in standard form has the leading term( first term) of the term with the largest exponent.
Other terms then follow in descending powers.
Given
5x² - 2 + 4 - 2x
The term with the largest exponent is - 2 ← becomes first term
Thus the polynomial can be expressed as
- 2 + 5x² - 2x + 4 ← in standard form
Answer:
Mona will save a total of $7 by going to Carpet World.
Step-by-step explanation:
First, we need to calculate the total area of the floor by multiplying the width by the length...
5m * 8m = 40m
Now we calculate the amount that it would cost to buy the carpet from each of the establishments. For the first establishment, we can buy 16 and get the next 8
half off and that would leave another 16
at full price. The second establishment we have a 5% off (0.95 of official price) for every 8
, since out total area is 5 times this amount then our total will have a 5% off.
Establishment 1: (16 * 2.20) + (8
* 1.10) + (16
* 2.20) = $79.20
Establishment 2: (40 * 1.90) * 0.95 = $72.20
Difference: 79.20 - 72.20 = $7
Mona will save a total of $7 by going to Carpet World.
