Two multiply 2 monomials, you have to multiply the coefficients and add the degrees. For example
2x^2 × 3x^3 =
6x^5
I'm not entirely sure about these, and the last one was tricky but i hope this helped.
The fraction would be 17over 21 but there is no number that goes into that unless you want a decimal
Answer:
The required equation is 
Step-by-step explanation:
Consider the provided information.
Let P represent the number of pages left to read after t hours.
Shryia read a 480-page-long book cover to cover in a single session, at a constant rate. After reading for 1.5 hours, she had 402 pages left to read.
Total number of page Shryia read in 1.5 hours is:
480-402 = 78
It is given that the rate is constant i.e 1.5 hours,
Therefore, she read 78 pages in 1.5 hours.
She can read
page per hour
The required equation is:

Where t represents the number of hours.
Answer:
x - 3
Step-by-step explanation:
Given

Note that x² - 9 is a difference of squares and factors as
x² - 9 = (x + 3)(x - 3), thus
Cancel the x+ 3 factor on the numerator/ denominator leaving
x - 3 ← in simplified form
