we know that
The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Let
s------> the length of the third side

therefore
<u>The answer part a) is</u>

we know that
the perimeter of a triangle is the sum of the length sides
In this problem

<u>For
</u>
the perimeter is equal to

<u>For
</u>
the perimeter is equal to

so

therefore
<u>the answer part b) is</u>

Whenever you see the word "per" you can ALWAYS substitue in the word "divide". When you see "miles per gallon", change "per" into "divided by" to get miles divided by gallons. That is how you will solve the problem.
SO.....
300 miles ÷ 10 gallons = 30 miles per gallon
we know that
If two numbers have a sum of zero, then we say they are additive inverses.
so
z+0.8=0 -------> the sum is equal to zero
z=-0.8------> the additive inverse of z is equal to -0.8

<u>the answer Part a) and part b) in the attached figure</u>
Answer:
The fraction is 41/99.
Step-by-step explanation:
The steps are :






Multiplication is like repeated addition! So add 33 four times.
33
+33
-------
66
+33
-------
99
+33
------
132.
So your final answer is 132. Hope this helps! Have a happy holiday!
