Answer:

The average of -2.5, 5.2, 1.7, and -0.8 is 0.9

Step-by-step explanation:

You are taking the mean of all the values

So you would add -2.5, 5.2, 1.7, and -0.8 all together

This gives you 3.6

Then you would divide by the number of numbers per se,

Which would give you the answer: 0.9

What is the area of this figure?

Alexxandr [17]

Answer:

The area of the figure is equal to $35\ cm^{2}$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of the figure is equal to the area of a square plus the area of a triangle

Find the area of the square

The area of square is equal to

$A=b^{2} =5^{2}=25\ cm^{2}$

Find the area of the triangle

The area of the triangle is equal to

$A=(1/2)bh=(1/2)(5)(4)=10\ cm^{2}$

therefore

The area of the figure is equal to

$25\ cm^{2}+10\ cm^{2}=35\ cm^{2}$
