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)

7*4 - 7^x
28-7x
Diagonals of rectangles are equal. AC = BD, so 2(x-3) = x+5. 2x - 6 = x+5. x = 11. Plug this into x+5 and you get 11 +5 = 16.
