A. (x+3)(4x+5) 
(multiply x with 4x+5 then multiply 3 with 4x+5)
=4x^2+5x+12x+15
=4x^2+17x+15
b,c, and d are similar
        
             
        
        
        
Answer:
 2x3 - 3x + 4
  ———————
       x2   
Step-by-step explanation:
Step  1  :
                   2
 Simplify   ——
                   x2
Rewriting the whole as an Equivalent Fraction :
 4.1   Adding a fraction to a whole
Rewrite the whole as a fraction using  x2  as the denominator :
            x             x • x2
     x =  —  =  ——————
             1                 x2

Answer:
start by mulitplying ten 5 times so 10x10x10x10x10=100,000. then multiply 100,000x3.8=380,000. and then times 300 so your ancwer is 114,000,000
