The first problem is true because with multiplication it doesn't matter which order it is in.
The second problem is false because you will get a different quotient depending on which numbers are on which side of the equation.
Answer:
no, it does not
Step-by-step explanation:
if it was a function, all the x values would've been different, but since 5 is repeated, it is not a function.
The answer would be : A parallelogram with congruent sides does NOT guarantee that a quadrilateral is a rectangle
The answer is 21 which comes from 7 * 3.
Draw the four points in a complex plane. From the drawing you can see that the lenght is 4i - (-3i) = 4i + 3i = 7i, and the width is 1 - (-2) = 1 + 2 = 3.
So, the area is 7 * 3 = 21.
