Answer:
(3x - 5)(x + 1)
Step-by-step explanation:
We need to factor 3x² - 2x - 5.
In order to do this, we must look at the factors of 3 and -5:
3 = 1 * 3
-5 = 1 * -5
Somehow, we need to pair up these so that they add to -2. We realize we can do this by multiplying 1 by -5 and adding that to 1 * 3:
1 * -5 + 1 * 3 = -5 + 3 = -2
So, we have (3x - 5)(x + 1).
Let, the height of the building be x ft.
Given the building casts 35ft shadow.
The height of the flagpole given which is 22ft and casts a shadow of 10ft.
Now to find the height of the building we have to equate the ratio of height and shadow of the building and the flagpole.
So we can write,
x/35 = 22/10
To find x, we have to get rid of 35 from the left side and have to move it to right side. As 35 is divided there, we will multiply 35 to both sides.
(x/35)× 35 = (22/10)×35
x = (22×35)/10
x = 770/10
x = 77
So, the height of the building is 77 ft which is the required answer here.
