Answer:
I think it's 49 I'm sry if I'm wrong hope you luck
Step-by-step explanation:
Answer:
well for the cats she can do 3 for each and dogs 2 for each
with the equation of the slope for two points given, m=Y2-Y1/ X2-X1, you can obtain the slope , x1= 3, y1 = -1 , x2= -1, y2= 2
m = 2-(-1)/ -1-3 ⇒ m= 3/-4, m = -3/4, therefore the slope is - 3/4

Explanation:
The triangle is isosceles, because (from the diagram) ∠
A
B
C
=
∠
A
C
B - note how the angle there is marked on both of these. If these angles are equal, this means that the sides
A
C
=
