Answer:
6x - 11 feet
Step-by-step explanation:
Dale is standing (2x + 7) feet height from the base of the tower.
And the tower is given to be (8x - 4)feet tall.
We have to find the distance between Dale and the top of the tower.
Now, the distance between dale and the top of the tower = height of the tower - height of Dale = (8x - 4) - (2x + 7) = (6x - 11) feet. (Answer)
$370.00 - $40.00 = $330.00
$330.00 - $50.00 = $280.00
$280.00 + $210.00 = $490.00
Ellen now has $490.00 as her new balance.
Using pythagoras theorem,
a^2 + b^2 =c^2
11^2 + 11^2 = c^2
c^2=242
c=
c= 15.556
c=15.6
