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.
-3(2)-3(2)3+-3(2)+2(2)3--3(2)
I got -12
Correct me if I'm wrong, but isn't it 1?
((1/5)/6)x6=1/5
The result is
3x^2 + 2 + 3/2x-1
If X and Y are two sets, then X × Y is the Cartesian product of X and Y, which is the set of all pairs (x, y) such that x ∈ X and y ∈ Y.
This means
A × A = {(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3)}
