Answer:
D. Discount Deals Depot; $15.20
Why?
Lets do Big Bargain Bonanza first.
$8.00 would stay the same as it is for handling. The only number that would change is $1.25, it uses the the words PER pound for shipping.
Your equation would look like this with p being how many pounds Kanya is shipping:
$8.00+$1.25p
Now we just plug in the numbers.
$8.00+$1.25(6)=
$8.00+$7.50=
$15.50
The same games for Discount Deals Depot.
$9.50+$0.95(6)=
$9.50+$5.70=
$15.20
So in conclusion Discount Deals Depot; $15.20 is cheaper than Big Bargain Bonanza;$15.50
Answer:
-5x^3 +11x^2-2
Step-by-step explanation:
(8x^2 − 1 + 2x^3) − (7x^3 − 3x^2 + 1)
Distribute the minus sign
(8x^2 − 1 + 2x^3) − 7x^3 + 3x^2 - 1
I like to line them up vertically from largest to smallest
2x^3 + 8x^2 − 1
− 7x^3 + 3x^2 - 1
-----------------------------
-5x^3 +11x^2-2
