So, since the polygons are similar, they will share a scale factor.
The dilation is a reduction.
SF= preimage/image
SF=48/40
SF= 1.2
To find the value of x, multiply 20 by 1.2, so:
20(1.2)=24
Thus, x = 24
Now, to check if the sides are proportional (this will determine if the polygons are, in fact, similar.)
24/20=1.2
48/40=1.2
BTW, the missing side measure for the image is 40 since 48 is its corresponding side, and 48/1.2 (SF) is 40.
Hence, we have 48/40= 1.2

I can't see all ur work that u showed so far
Answer:
y intercept = 4
x intercept = 1/3
<u>x - intercept</u>
To find the x intercept, substitute 0 for y and solve for x.
0 = -12x + 4
0 = -12 (1/3) + 4
0 = -4 + 4
0 = 0
The x - intercept is 1/3
<u>y - intercept</u>
To find the y intercept, substitute 0 for x and solve for y.
y = -12 (0) + 4
y = 0 + 4
y = 4
The y - intercept is 4.
The area is 289.22 units squared
