Marty read 4 times as many pages as Nelson and Jennifer COMBINED. Marty read 1,860 pages. 
In total, after dividing Marty's total by 4, Jennifer and Nelson both read a total of 465 pages. 
After subtracting Nelson's 240, Jennifer is then found to have read 225 pages. 
B would be the best viable option, as it clearly shows that 240+?x4=1,860, which it does. 
Hope this helped. Khan Academy is a great resource for any learner. :)
 
        
                    
             
        
        
        
Complementary angles add up to equal 90 degrees. Knowing this, you can subtract 68 from 90. 90-68=22.
Hope this helps.

Answer:
(x + 2)²(x - 3)² = 0
Step-by-step explanation:
Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
