Answer:

122.24 is the approximate answer

Step-by-step explanation:

The Logo is made up of 2 semicircles and 1 rectangle

Two semicircles make one circle

The formula for a circle is π $r^{2}$

The radius (r) is 4 because the diameter is 8

so you plug it in and get 16π

The approximate value of π is 3.14

16 times 3.14 is 50.24 $cm^{2}$

so to calculate the area of the whole logo just add $72cm^{2} +50.24cm^{2} =122.24$

Answer:

Answer is in the explanation

Step-by-step explanation:

I don't know exactly word from word what your choices look like...

but I can describe per each box what happened in my own words:

First box: They multiply first equation by 3 and the second equation by 2 to obtain the equations in that first box.

Second box: They subtracted the two equations in the first box to obtain 1x+0y=2 which means 1x=2 or x=2 (this is called solving a system by elimination

Third box: They used their first original equation (before the multiplication manipulation) and plug in the value they got for x which was 2 giving them 3(2)-2y=10

Fourth box: They simplified the equation 3(2)-2y=10 by performing the multiplication 3(2) giving them 6-2y=10

Fifth box: They subtracted 6 on both sides giving them -2y=4

Sixth box: They divided both sides by -2 giving them y=-2

I will summarize then what I wrote above:

1st box: Multiplication Property of Equality

2nd box: Elimination

3rd box: Substitution (plug in)

4th box: Simplifying

5th box: Subtraction Property of Equality

6th box: Division Property of Equality
