If you want integer coefficients only, multiply the equation of the line by 10. I'm assuming you accidentally left off the "= 0" at the end: -1.7x + 8.5 = 0.
If that's the case, then multiplying the whole equation by 10 results in -17x + 85 = 0.
Here you have only integer coefficients.
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

Its D since 6 would go to both numbers in the parentheses.
Answer:
2.24
Step-by-step explanation:
If you look at the points on the graph, you can see that the distance between them is also the hypotenuse of a right triangle, meaning you can calculate the distance using the pythagorean theorem.
Answer:
Step-by-step explanation
The length of the left sloping line
= √ (5^2 + 7^2) = √74.
The right sloping line
= √(5^2 + 5^2) = √50.
So the perimeter:
= √74 + √50 + 2 + 2 * 4 + 14
= 39.67 to nearest hundreth.
Area = 1/2 * 5 * 7 + 2*5 + 1/2 * 5 * 5 + 4*14
= 96.
