The total height in feet of the  piece of plywood is 14 foot.

<h3> Pythagoras theorem</h3>

The theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the square of the other two sides.

The Pythagoras theorem: a² + b² = c²

where a = length

b = base

c = hypotenuse

13² = 5²  + h²

169 = 25 + h²

h²  = 169 - 25

h²  = 144

h = √144

h = 12 foot

<h3>Height of the plywood </h3>

12 + 2 = 14 foot

At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.

Let x be  the amount of one of Derek's withdrawals

Each of John's withdrawals was $5 more than each withdrawal that Derek made.

x + 5 is t the amount of one of John's withdrawals

Derek made 7 withdrawals

So amount withdraw 7 times = 7x

John made 5 withdrawals

So amount withdraw 5 times = 5(x+5)

Both Derek and John withdrew the same amount of money in the end

(A) 7x = 5(x+5)

(B) Solve for x

7x = 5x + 25

Subtract 5x from both sides

2x = 25

Divide by 2

x = 12.5

(C) check your solution

we plug in 12.5 for x in 7x= 5x + 25

7(12.5) = 5(12.5) + 25

87.5 = 62.5+ 25

87.5 = 87.5

(D) Each brother withdrawal 87.5 dollars
