Answer:
12
Step-by-step explanation:
This is a joint variation problem:
z varies directly as x and y
Interpreting this;
z ∝ xy
Therefore;
z = kxy
z = 6, x = 2, y = 6
Now find k,
6 = 2 x 6 x k
6 = 12k
k = 
To find the value of z;
x = 3, y = 8
z = x 3 x 8 = 12
Answer:
9 over 5
Step-by-step explanation:
Answer:
-6 and -5 (There are many more combinations of numbers that can equal to -11 but this is just one of the many possibilities.
Step-by-step explanation:
-6 and -5
See you can write it like this,
-6+ (-5)
= -6-5
=-11
If you mean proof that the opposite sides of a parallelogram are equal, you draw a diagonal then prove that the 2 triangles formed are congruent.
