A^2 + b^2 = c^2
9^2 + 12^2 = 225
square root of 225 is 15
First, you have to simplify the equation:
y+3 = 3(x+5)
y+3=3x+15
So you multiply what’s inside the brackets (x+5) by the factor (3). So 3•x=3x, 3•5=15.
Then you rearrange the equation as necessary to convert it into standard form, which is Ax + By = C
Equations:
m = k + 5
k = s + 2
m + k + s = 30
-----------------------
Substitute for "m" and for "s"::
k+5 + k + k-2 = 30
3k +3 = 30
3k = 27
