245.76
Step-by-step explanation:
Answer:
36 degrees for each angle.
Step-by-step explanation:
If you divide 180 by 5 (for each point in the star) you get 36 degrees.
60 degrees, because it's an equilateral triangle, as you can tell because the sides are all the same length.
Answer:
Check explanations
Step-by-step explanation:
For all real numbers a,b, and c, the distributive property states that:
For Part A, we have
Or
For Part B, we have
-4(3x-10)+5(2-6x)=-4*3x--4*10+5*2-5*6x
This simplifies to:
-4(3x-10)+5(2-6x)=-12x+40+10-30x
-4(3x-10)+5(2-6x)=-12x-30x+40+10
-4(3x-10)+5(2-6x)=-42x+50
For the C part, we have:
For Part D, we have:
We simplify to get:
Simplify further to get:
Answer: Rational number
Step-by-step explanation:
Let's write out the properties of rational and irrational numbers.
Rational
- Integers
- Whole numbers
- finite decimals
- repeating decimals
Irrational
------------------------------------------------------------------------------------------------------------
Looking at the list we made, we can say that -20 is a rational number. -20 is an integer and a whole number. Therefore, it is a rational number.
