A. and x = 9

To solve the equation, you would need to isolate the variable, so the first step would be to add six to each side.
2x = 18
Then, divided each side by 2 to get the value of x.
x = 9

Answer:

4.9 feet

Step-by-step explanation:

First, we need to determine the height of the building using the following:

L^2 = H^2 + B^2

Where

H = Height of the building

L = Length of the first ladder = 20ft

B = Distance from the base of the building = 10ft

So, we have:

20^2 = H^2 + 10^2

400 = H^2 + 100

H^2 = 400 - 100

H^2 = 300

H = \sqrt{300

Next, is to determine the distance of the new ladder from the base of the building (B) using Pythagoras theorem using:

L_2^2 = H^2 + B_2^2

Where

L_2 = 18 --- Length of the second ladder

H = \sqrt{300 ----- Height of the building

So, we have:

18^2 = \sqrt{300}^2 + B_2^2

324 = 300 + B_2^2

B^2_2 = 324 - 300

B^2_2 = 24

Solving for B2, we have:

B_2 = \sqrt{24

B_2 = 4.9
