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

Let the numbers be x and x + 1.
From the given information,






But, as we know -5 is not a natural number,
Hence, x = 4 .
<u>So the 2 unknown numbers are</u><u> </u><u>:</u>
- x + 1 = 4 + 1 = 5 [2nd number]

He saved $1.75 per book.
($57.75/7) - ($45.50/7)
$8.25 - $6.50 = $1.75
Answer is B. 4,096
I encountered this problem before. This is a trick question.
84 is not really the number 84. It is 8 raised to the 4th power.
So 8⁴ is equal to 4,096.
8 x 8 x 8 x 8 = 4,096
8 x 8 = 64
64 x 8 = 512
512 x 8 = 4,096
