What is the value of 3x 2 squared + 5x when x=3 cassie's book has 325 pages. she read 155 pages yesterday and the rest today. write an equation to express how many pages she read today. show your work

155 + p = 325

Step-by-step explanation:

Before we find the value of  

3 x , let's first find the value of  x

To do so, first, combine  

3 x + 5 x : 8 x − 2 2

Add  

2

to both sides of the equation:

8 x − 2 +  2 = 2 + 2

8x=4

Now divide both sides by  8 :

Since we want 3x, multiply that by 3:
