So first we remove 7.00$ from 19.00$
Now we have 12.00$
Then it said 1.50$ per hour
So we do 12 divide 1.50. 12:1.50= 8
He can skate for 8 hours
Area= length*width
width=W
W*(3W-4)=615
3W^2-4W=615
3W^2-4W-615=0
W=41
W=-45
But W cant be a negative number so it is 41m (width)
The length is (41*3)-4=119m (length)
Y +6 = -7/6 (x-4)
Mark brainliest please
Hope this helps you
