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
Answer:
The length of the rectangle is of 9 units.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots 
such that 
, given by the following formulas:
Area of a rectangle:
A rectangle has width 
and length 
. The area is the multiplication of these measures, that is:
The length of a rectangle is the sum of the width and one.
This means that 
, or 
The area direct angle 72 units. What’s the length, in units, of the rectangle
We want to find the length. So
Quadratic equation with 
. So
Since the length is a positive measure, the length of the rectangle is of 9 units.
The equivalent fraction for 0.7 is 70/100.
You know this because 0.7 is the same as 7/10.
7/10 is the same as 70/100 when we create 7 groups of 10 (numerator) and 10 groups of 10 (denominator).
Also, placing a zero to the right of any number on the right hand side of the decimal point will not change the value.
0.70 is 70/100
