Answer:
<em>AB = 5√2</em>
<em>AC = √145</em>
<em>BC = √65</em>
Step-by-step explanation:
Using the formula for calculating the distance between two points
D = √(x2-x1)²+(y2-y1)²
For AB A(-3,6),B(2,1),
AB = √(2+3)²+(1-6)²
AB = √(5)²+(-5)²
AB = √25+25
AB = √50
<em>AB = 5√2</em>
For AC A(-3,6) and C(9,5)
AC = √(9+3)²+(5-6)²
AC = √(12)²+(-1)²
AC = √144+1
<em>AC = √145</em>
For BC B(2,1), and C(9,5)
BC = √(9-2)²+(5-1)²
BC = √(7)²+(4)²
BC = √49+16
<em>BC = √65</em>

<em>Since All the sides are difference, hence triangle ABC is a scalene triangle</em>
Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.
Answer:
(set up a ratio)
54/x = 18/100
(cross multiply)
18x = 5400
(solve for x)
x = 300 miles
