There are six important properties of parallelograms to know:
<span>Opposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.<span>Each diagonal of a parallelogram separates it into two congruent triangles.</span></span>
Answer:
Step-by-step explanation:
The instants when hovercraft lands on the ground are those when h(x) = 0. Given that height function is a second-order polynomial in its factorized form, such instants are related to the roots of the function.
Time is a positive real number and the only possible solution:
Card A:
<span>$4,350 x 0.02 = $87
</span><span>$360 - $87 = $273
Card B:
Interest $270 no rebate
so $273 - $270 = $3
Card B cost least and $3 less than card A</span>

Answer:
There are 150 blue marbles in Alex's bag.
Step-by-step explanation:
Let 
, 
, 
be the quantities of red, blue and yellow marbles, respectively. From statement we derive three rational equations for initial and final ratios:
Initial ratio
(1)
(2)
Final ratio
(3)
After some algebraic handling we get the following system of linear equations:
(1)
(2)
(3)
The solution of the system of linear equations is:
, 
,
