A parallelogram is usually defined as a quadrilateral with 2 pairs of equal, opposite and parallel sides. It can also form right angles between adjacent sides. Therefore, not all rectangles are squares, not all parallelograms are rectangles.

Hope I could help! :)

Answer:

Sometimes, but not always.

Step-by-step explanation:

A parallelogram is a quadrilateral with two pairs of parallel sides, but there are no requirements for its interior angles. A rectangle, on the other hand, <em>must</em> have four interior 90 degree angles. So a rectangle is always a parallelogram, but a parallelogram is not always a rectangle.

Solve the following system of linear equations.

andrey2020 [161]

To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.

First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3

Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42

Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3

Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8

So, we can conclude that the correct answer is B. (-8,3)
