A ladder is leaning against a wall. The top of a ladder is 5m off the floor and the base of the ladder is 1m away from the wall. How long is the ladder? Give your answer to one decimal place.

The ladder is 5.09 m long

Step-by-step explanation:

Given that,

The height of the wall, P = 5 m

The base of the ladder is 1 m away from the wall.

We need to find the length of the ladder. Let it is H. We can solve it using the Pythagoras theorem. It can be given by :

So, the ladder is 5.09 m long.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
