For #2:
<span> 3x^2 + 4 – 2x^2 + 6</span>
<span><span>You need to combine your like terms:
</span>
3x^2 – 2x^2= x^2</span>
4 + 6 = 10
This will now give you:
<span>X^2 +10</span>
I think 1 / 7 x 7 is the correct answer
Change the numbers into percents
0.3-----30%
26%---26%
1/5-----20%
0.09-----9%
Answer:
70% off
Step-by-step explanation:
Calculate both these deals, then figure out which costs less.
1. 70% off
- (70% = .70)
- 70% of 998.97 = .70 * 998.97 = $699.279 is the discount
- Subtract this from 998.97: 998.97 - 699.279 = <u>$299.691</u>
2. $650 off
- Subtract 650 from 998.97: 998.97 - 650 = <u>$348.97</u>
This makes sense, because 650 is 65% of the original cost, which is less than 70%!
