Answer:
Option D. a^2+6ab-2ba
Step-by-step explanation:
Option D because we have like terms: 6ab and -2ba=-2ab, then
a^2+6ab-2ba=a^2+6ab-2ab
Simplifying on the right side of the equation adding like terms:
a^2+6ab-2ba=a^2+4ab
X = -5
The goal of this problem is to solve for x.
To solve x in this problem you need to find a way to get it by itself on the left side, the way to do this is divide -5x by -5.
You then also have to do the same for the right side. This gives you -5.
Answer:
$719.95
Step-by-step explanation:
To find the purchase total, multiply the price by the percent paid and add the percent of tax.
The store offers a 20% discount. This means you pay 80% of the price. So the discounted price is 0.80(849) = 679.2.
Find the tax to be paid by multiplying 0.06(679.2) = 40.752.
Add the tax for the final total.
679.2 + 40.752 = 719.95
5x-15-2x=6
3x=21
x=7
Therefore, x must equal 7.
