Answer:
10
Step-by-step explanation:
The distance formula is useful.
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100
d = 10
The distance between P and Q is 10.

<em>Additional comment</em>
You may recognize the run : rise ratio of 6 : 8 = 3 : 4. This suggests a 3-4-5 right triangle with a scale factor of 2. If you're familiar with that Pythagorean triple, you can write down the answer as soon as you see the rise and run numbers.
Answer:
$504
Step-by-step explanation:
Step one:
given data
A shirt that cost $420
we are told that the shirt was on a discount sale of 20%, so when the discount is over the price will return to $420, we are then told that the shirt was marked up 20%.
Step two:
Hence the new cost is
=20/100*420+ 420
=0.2*420+420
=84+420
=$504
Would have to go with x=5
Answer:
The third option with the right angle
Step-by-step explanation:
By creating a perpendicular line through the line of reflection (the orange dotted line) and the point "D" we can measure the distance of D from the line of reflection. Then draw "D'" using the distance of the "D" from the line of reflection.
