Answer:
6 and 18
Step-by-step explanation:
a+b=24
5a-b=12
5a+a=6a
24+12=36
6a=36 so A on it's own is 6
24-6=b
b=18
hope this helps!
Bottom answer 2/5 and 7/8
Answer:
W'' = (2, -3)
Step-by-step explanation:
Reflection over the x-axis negates the y-coordinate and leaves the x-coordinate alone. The W becomes ...
... W' = (-2, -3)
Reflection over the y-axis negates the x-coordinate and leaves the y-coordinate alone. The W' becomes ...
... W'' = (2, -3)
The points are (-3,3) and (2,2) then you use distance formula to find the distance between them
Answer:
8
Step-by-step explanation:
For the smallest possible length, this has to be one of the shorter sides. Let the length of this side be x.
So, by the triangle inequality theorem, 1+x>8, which means x>7.
So, the smallest possible whole number length is 8.
