58,320.3 is the answer in my hole
Answer:
c
Step-by-step explanation:
The
Least Common Denominator (also called
LCD) is very important to
working with rational expressions. The process we use to find the LCD of the exponents is based
on the process used to find the LCD of intergers. For instance, to find the LCD of 8 and 6 you need:
1. Consider multiples of the larger number
8, 16, 24,...
2. 24 is the first multiple of 8 that is also divisible by 6
3. Then 24 is our Solution.
To answer the question regarding expressions with exponents let's take an example:
Find the LCD of
:
1. 12 is the LCD of 4 and 6
2. Use all variables with highest exponents on each variable, then
3. Finally,
solutions is:
So we know that the length of the rectangle is 9 meters.
In order to find area of a rectangle, you multiply the length by the width.
To find the width, you divide the area by the side you do have , which is 9 meters.
72 divided by 9 is 8.
So the width 8 meters, and now to find the perimeter you must add all sides of the rectangle.
9+9+8+8 = 34.
The perimeter of the rectangular garden is 34 meters.
Use order of operations or PEMDAS
this is order of simplification
work from left to right
Parentahsees (grouping symbols)
Exponents
multiplication or division
addition or subtraction
so
replace a with 1, b=2 and c with -8
now exponents
multiply and divide, working from left to right (remember, division is multiplication by a fraction)
addition and subtraction
