Answer:

A: 171.75

B: 170

Step-by-step explanation:

The mean (or average) can be found by...

- add all the numbers together (we will call this y)

- divide the total sum (or y) by the total amount of numbers used to add

Formula:

(x₁ + x₂ + x₃ + ... + xₙ) ÷ n

For A:

(172 + 130 + 173 + 212) ÷ 4 = 171.75

For B:

(136 + 184 + 168 + 192) ÷ 4 = 170

Answer:

Step-by-step explanation:

So, when we dilate a triangle, it affects side measures.

So let's find it!

$10*0.4=4$

$30*0.4=12$

So, the sides of our new triangle is 4 and 12.

Let's find the area!

$\frac{4*12}{2} =24$

So, it is the first option! Hope this helps!

P.S. Stay Safe
