Hello!
This makes a triangle
The cat is 20 ft high
The triangle is 20 feet high
The is 6 ft between the ladder and the tree
The base is 6 ft long
You use the Pythagorean theorem to solve this

a and b are the base and height
put in the values you know

square the numbers
36 + 400 =

Add
436 =

Take the square root of 436
20.9 = c
Since this is lower than the length of the ladder the ladder is long enough
The answer is yes
Hope this helps!
Yup c the brainliest you say
Answer: yes
Step-by-step explanation: Because the negative 12 is on the left of the zero it will always be smaller than any number greater than zero.
Answer:
<h2>A. -2y+5x/3x-2y</h2>
Step-by-step explanation:
Given the complex fraction;

First we will find the LCM of the numerator and the denominator as shown below;

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

This gives the required answer
The matrices are
S =(4 11 T= ( -8 11
-3 -8) 3 4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
ST will be
( 4 11 × (-8 11 = ( 1 0
-3 -8) -3 -4) 0 1)
and also TS
( -8 11 × (4 11 = ( 1 0
-3 -4) -3 -8) 0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I
