How long must a ladder be if it is to be leaned against a house at a point 9 ft above the ground resting 3 ft from the bottom edge of the wall?

9.5 feet

Step-by-step explanation:

We have that,

Height of the point at the wall where the ladder is leaned = 9 feet

Horizontal distance between the ladder and wall = 3 feet.

So, we get the right triangle as shown in the figure.

Using 'Pythagoras Theorem', i.e. , we get,

i.e.

i.e.

i.e. x = 9.5 feet.

Thus, the length of the ladder must be 9.5 feet.

answer: you have to send a photo of the question

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
