What is the difference of the polynomials?<br><br>(8r6s3 – 9r5s4 + 3r4s5) – (2r4s5 – 5r3s6 – 4r5s4)
nignag [31]
(Distribute the minus sign of the subtrahend in each term.)
= 8r⁶s³ – 9r⁵s⁴ + 3r⁴s⁵ – 2r⁴s⁵ + 5r³s⁶ + 4r⁵s⁴
(Add or subtract like terms.)
= 8r⁶s³ – 5r⁵s⁴ + r⁴s⁵ + 5r³s⁶
(If you want to factor out, then...)
= r³s³ (8r³ – 5r²s + rs² + 5s³)

The regular price of a watch is $42.25. During a sale, the watch rang up for 29.95. What was the percent off the watch during th
kupik [55]

Answer:

(d) The sale was for a 29% decrease.

Step-by-step explanation:

Original/Regular price = $42.25

New/Sale price = $29.95

Difference in prices = 42.25 - 29.95 = 12.3

Formula for finding the percentage decrease of the sale

= \frac{Difference  in  prices}{Original/Regular  price} × 100

\frac{12.3}{42.25} × 100

= \frac{1230}{42.25}

≈ 29.11 %

≈ 29 %

Therefore, the percent off the watch during the sale was approximately 29%.
