Answer:
2.72 x 10^4
Step-by-step explanation:
2.4 x 10^4
= 24000
3.2 x 10^3
= 3200
Therefore,
(2.4 x 10^4) + (3.2 x 10^3)
= 24000 + 3200
= 27200
= 2.72 x 10^4
 
        
             
        
        
        
Answer:
(x−3)(x−5)
Step-by-step explanation:
Let's factor x2−8x+15
x2−8x+15
The middle number is -8 and the last number is 15.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -8
Multiply together to get 15
Can you think of the two numbers?
Try -3 and -5:
-3+-5 = -8
-3*-5 = 15
Fill in the blanks in
(x+_)(x+_)
with -3 and -5 to get...
(x-3)(x-5)
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The volume of a box is equal to the length l times the width w times the height h.

Substitute the values of the length l=8, the width w=2, and the height h=4 into the formula.

Multiply 8 by 2.

Multiply 16 by 4.

Hence, the volume of the rectangle prism is 64(in)³.
