Answer:
25m^3n^7
Step-by-step explanation:
Let's write out the equation
5mn^4 • 5m^2n^3
When we multiply exponents with similar bases, you add them together.
For example 2^2 • 2^2= 2^4
Numbers with no exponent are to the power of one
For example: 2= 2^1
Now that we know this, let's combine like terms
5 • 5=25
m^1•m^2=m^3
n^4•n^3=n^7
Answer: 25m^3n^7
 
        
             
        
        
        
A normal distribution is symmetrical about the mean. Therefore half of all young men are shorter than 68 inches.
        
                    
             
        
        
        
Answer:
x = -11/9
Step-by-step explanation:
7(x+3)=-2(x-5)
Distribute
7x+21 = -2x+10
Add 2x to each side
7x+21 +2x = -2x+10+2x
9x +21 = 10
Subtract 21 from each side
9x +21-21 = 10-21
9x = -11
Divide each side by 9
9x/9 = -11/9
x = -11/9
