Answer:
Step-by-step explanation:
rewrite as multiplication
look to factor
, difference of 2 squares and perfect square
, finish factoring and simplify
2(x+3)
Step 1
<u>First situation</u>
when a ladder is leaning against a wall
Let
x-------> the distance of the bottom of the ladder from the wall
L-------> the length of the ladder
<u>Find the length of the ladder</u>
Applying the Pythagorean Theorem
------> equation
Step 2
<u>Second situation</u>
when the ladder will be lying flat on the ground
<u>Find the length of the ladder</u>
In this situation the length of the ladder is equal to
square both sides
------> equation
Step 3
equate equation and equation
therefore
<u>the answer is</u>
the length of the ladder is
see the attached figure to better understand the problem
Your answer would be
A) 20.3
i am not sure about this but yeah also can i have brainliest
Answer:
L=35cm
Step-by-step explanation:
Perimeter is 2(L+w)
156cm=2*(43+L)
L=35cm
I believe it is 16 since if you do 21-5 it is 16 :)
