Answer: the awnser is 9, 40, 41 mark me brainlist
Step-by-step explanation:
Sum of the squares of the two side = Square of longest side
a² + b² = c²
a)
So let's check 7, 24, 25
Is 7² + 24² = 25² ?
7*7 + 24*24
49 + 576
=625.
Let us perform the other side 25²
25² = 25 * 25 = 625
Therefore the left hand side = Right hand side.
Therefore 7, 24, 25 is a Pythagorean Triple
b)
Let's check 9, 40, 41
Is 9² + 40² = 41² ?
9² + 40²
9*9+ 40*40
81 + 1600
=1681
Let us perform the other side 41²
41² = 41 * 41 = 1681
Therefore the left hand side = Right hand side.
Therefore 9, 40, 41 is a Pythagorean Triple.

For this case, the first thing you should know is that there are two possible cases:
Case 1:
If 0 <k <1 then there is a reduction of the orignal figure.
Case 2:
If k> 1 then there is an expansion of the originial figure.
Therefore, in this case, the scale factor that represents a reduction is given by:
k = 3/4 = 0.75 (0 <k <1)
Answer:
the dilation that would represent a reduction is:
C. k = 3/4
I think answer should be d. Please give me brainlest let me know if it’s correct thanks bye
We know that area of rectangle its equail A=l*w.
We know that length is 4 times greater than width, so we can say
l=4x and w=x
Knowing that area A=144 we can say
4x*x=144
-
w=6 - its the width
l=6*4=24 - its the length
