The answer might be slope.
Triangle ABD and ADC are righttriangles so u can use the Pythagorean theorem/triples. the triples are 3/4/5 and 5/12/13. 12 is 4x3, and 15 is 5x3, so BD is 3x3, which is 9. AC is 13, as it is part of the Pythagorean’s triples
Answer:

Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line

Let's simplify the equation of the line to get:


The slope of this line is -5.
The perpendicular to this line has a slope of

The equation going through (6,-10) is

We substitute to get;

Expand;


Answer:
The answer is x - 13y
Step-by-step explanation:
Start by writing it out like this:
17.50
<u>* 2.48 </u>
Make sure that all the places are in correct order. Notice that I added a ZERO in the place that had nothing there.
Move the decimal point so everything is a whole number. You have moved it 4 times.
Now, starting from 8, multiply it by 0, then 5, then 7, and lastly, 1. Now go to the next number (4) and do the same, this time though, put a zero in the first spot. Every new number, add another zero.
After you are done, add them up. Now move the decimal point starting from the right and into the number 4 times. Take out the zeros.
Your answer should be: 43.4
