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>

Answer:
6.12
1.39
4.12
12
Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is
