Answer:
see below
Step-by-step explanation:
The area of a square is
A = s^2
(9x2 − 12x + 4) = s^2
Rewriting the left side by recognizing a perfect square trinomial
a^2 -2ab - b^2 = ( a-b) ^2
( 3x -2) ^2 = s^2
Taking the square root of each side
3x-2 = s
The side length is 3x-2
The area of a rectangle is
A = l*2
25x^2 − 16y^2 = l*w
(5x)^2 - (4y)^2 = l*w
Rewriting the left side by recognizing a difference of squares
a^2 - b^2 = ( a-b) (a+b)
( 5x-4y) (5x+4y)
The dimensions are ( 5x-4y) by (5x+4y)
So the way you would find it is a ratio.
1.
2. =(6)(17)/(2.5)
3. =102/2.5
4. =40.8
So the building would be 40.8 feet tall.
Answer:
you multiply the length then the width and height
