In geometry, a parallelogram is defined as a simple quadrilateral with two pairs of parallel sides, with opposite sides are of equal length and the opposite angles of equal measure. From these descriptions alone, one statement is true-- <span>All squares are parallelograms because they have 2 pairs of parallel sides.</span>
Answer:
Step-by-step explanation:
x^3-2y^2-3x^3+z^4
(3)^3-2(5)^3+(-3)^4
-142
Answer:
16
Step-by-step explanation:
you would get c alone so you subtract 5 to the other side
When y varies inversely as x ⇒ y*x=k
y=27 and x=40 ⇒27*40=1080=k
y*10=1080
y=1080:10
y=108
Answer:
20
Step-by-step explanation:
The pythagorean theorem states that
So 
You would then do
Because a square root is the opposite of a square.
because 20 * 20 = 400
