Answer:

B) x = 3

Step-by-step explanation:

lets plug in the first option to see if it works

3x=9

3*27=9

thats not right ( 3*27 = 81 )

Next, we try the second option

3x=9

3*3=9

that looks more like a resonable answer right?

now to check our work

3+3+3=9

Its correct!

Hope that helps

The Montgomery Company tells Squeaky Clean that most of their buildings are 40 feet tall. Squeaky Clean decides to use ladders t

Soloha48 [4]

Answer: 41 feet

Step-by-step explanation: The ladder, the building and the sidewalk creates a right triangle, with the 90° formed at the junction of sidewalk and building, so the length of the ladder is the triangle's hypotenuse.

To determine hypotenuse, use Pythagorean's theorem:

$h^{2}=s^{2}_{1}+s^{2}_{2}$

$h=\sqrt{40^{2}+9^{2}}$

$h=\sqrt{1681}$

h = 41

For the ladder to reach the top of the building, it has to be 41 feet tall.
