Factor the binomial. 9x^4-64

Mathematics
1 answer:
kap26 [50]3 years ago
8 0

Answer:

The answer is the first one

Step-by-step explanation:

This is a difference of squares, meaning the first term is a perfect square, and the second term would be a perfect square if it were not negative. To factor it, find the square root of both the first an second term, the square root of 9x^4 is 3x^2 and the square root of 64 is 8. Put both of those numbers into 2 separate sets of parenthesis and one set will have + in between and the other will have -. It will look like the first option

Jason and his friend went to a restruant for dinner. The food that they ordered cost $25. A 7℅ sales tax was applied to the tota
Westkost [7]
$30.76

Find 7% of $25 = (25/100) x 7 = 1.75, then add it to $25 because it's applied tax.

25 + 1.75 = $26.75

15% = split into 10 and 5 percent
10%= (26.75/10) = 2.675
5% = 1.3375, make sure you add this all in your working out.

2.675 + 1.3375 = 4.0125

4.0125 + 26.75 = 30.7625 then round it to two decimal places because it's money :)
