Radius would be 19.9151730644
Since the equation is in slope-intercept form, we know from the definition of slope-intercept form that 6 is the y-intercept.
You forgot to add in your height to your question. To find your area you need to do 8 + 14 and get 22 then you nee to do the height divided by two. If you give me the height of the triangle I can tell you the area.
You are using the distributive property so you will multiply all the numbers in the parentheses by 5. So the end expression would be 30m+20n-15p
