Vertex is (4,0)
Fhats all I know
4,950×3=1650
1650÷100=16.5
his commission is $16.5
First add 7d to both sides:
-22 = 11d
Now divide by 11 both sides
-2 = d
You can work on either side of the equation, I used the right side for the variables because it was easier to add to positive numbers than dealing with negative numbers on the left side:
-7d -4d = 22
-11d =22
d = -2
either way you get the same answer :)
Take the root of both sides and solve.
A is 6 because so is the side across from it
And B is 8 because it the same size just flip it
Brainliest would be appreciated
