Answer:
a). y = 4.5
b) Scale factor = 
Step-by-step explanation:
a). Since, polygon Q is the scaled copy of polygon P
Both the figures will be similar.
Therefore, their corresponding sides will be proportional.

If x = 6,

y = 
y = 4.5
b). Since, polygon Q is the scaled copy of polygon P,
Polygon Q will be the image of preimage polygon P.
Scale factor = 
= 
Total earning in the summer = $1440
Step-by-step explanation:
Earning per hour for Samuel = $7.50
No. of hours worked in a day = 6
Earning for a day = Earning per hour for Samuel *No. of hours worked in a day
Earning for a day = $7.50 *6 = $45
___________________________________________________
No of days worked in a week by Samuel = 4
Earning for week = Earning for a day *No of days worked in a week by Samuel
Earning for week = $45*4 = $180
_____________________________________________________
No. of weeks worked in summer = 8
Total earning in the summer = Earning for week *No. of weeks worked in summer
Total earning in the summer = $180*8 = $1440 (Answer)

Don't know if this will help but if you cut it from corner to corner it will make a triangle
The given equation is an equation of a circle because it looks similar to the general equation of a circle.
<h3>What is the general equation of a circle?</h3>
The general equation of a circle is:
x² + y² +2gx + 2fy + c = 0...........eq1
Where (-g, -f) is the center of the circle.
c is a constant
Given equation is
3x² +6x + 3y²+7y+4 = 0
Let us take 3 as common
x² + 2x+y²+7/3y + 4/3 = 0
Let us rearrange the equation
x² + y²+2x +7/3y + 4/3 = 0...........eq2
Now look at eq1 and eq2
We got that eq2 is having a similar pattern as eq1.
Therefore, The given equation is an equation of a circle.
