Answer: a = 8; b = 15; c = 17
Step-by-step explanation:
c = b + 2 and c = 2a + 1
b = c − 2 and a = 
c² = b² + a²






c = 1 or c = 17
If c = 1 then b = 1 - 2 = -1, that's not possible
So x = 17
b = 17 - 2 = 15
a = 
Length sides of the triangle are 17 cm, 15 cm and 8 cm.
I saw some of this on a site but I want to make sure its correct so we're gonna apply the pythagorean theory and see if its correct.

This shows that this is correct.
Hope this helped! Again, some of this was from a site, not from me.
Given:
The line passes through (-3,-6) and (2,-2).
To find:
The equation of line.
Solution:
If a line passes through two points
, then the equation of line is

The line passes through (-3,-6) and (2,-2). So, the equation of line is




Subtract 6 from both sides.




Therefore, the equation of line is
.

Answer: the charge would be the same after 5 miles
Step-by-step explanation:
Let x represent the distance at which both companies charge the same amount.
company A charges a flat fee of four dollars plus 2 dollars per mile. It means that the total charge for x miles would be
4 + 2x
Company B does not charge a flat fee but charges $2.80 per mile driven. It means that the total charge for x miles would be 2.8x.
For the charge to be the same, the number of miles would be
2.8x = 4 + 2x
2.8x - 2x = 4
0.8x = 4
x = 4/0.8
x = 5
