If a quadrilateral is a parallelogram then opposite sides are parallel. For example, look at the diagram I provided below. If quadrilateral A,B,C,D is a parallelogram, then side A,B is parallel to side D,C. Also, side A,D must be parallel to side B,C.

Hey there! :D So you're wondering how you can tell if a quadrilateral is a parallelogram, right? Well, you are about to find out! The way you can tell whether a quadrilateral is a parallelogram because we know that a quadrilateral has 4 sides, right? And a parallelogram is a figure with opposite sides that never intersect or cross. So for example, a square is a quadrilateral and it has 4 equal sides and if we extend the lines horizontally, the would not cross.

I hope this makes sense to you! Have a good evening!(If you are in the US, but if you aren't, good morning!) :D

G(a/2)= 2(a/2)-3
=2a/2-3
then just subtract 2a/2 by 3/1 by finding the common denominator and same for the next one.

For question 39 & 40, we need to use the below equation to complete the sentence

$l=m\sqrt{n}$

Question 39:

When ' n ' increase, the $\sqrt{n}$ will also increase and that multiplied with constant ' m ', the l will also increase.

Solution for question 39:

As $n$ increases and $m$ stays constant , $l$ <u>increases</u>

-------

Question 40:

Solving the equation for m, we get

$l = m\sqrt{n} \\ \\ m=\frac{l}{\sqrt{n}}$

When ' l ' increases, the numerator increase, the denominator stays constant because 'n' stays constant, for this condition, the fraction increases.

Solution for question 40:

As $l$ increase and $n$ stays constant, $m$ <em><u>increases</u></em>

------

For question 41 & 42, we need to use the below equation to complete the sentence

$r=s^2/t^2$

Question 41:

When $s$ is triped, the equation will be...

$r=(3s)^2/t^2=\frac{3^{2}s^{2}}{t^2} =9s^2/t^2$

Solution for question 41:

If $s$ is tripled and $t$ stays constant, $r$ is multiplied by <em><u>9</u></em>

--------

Question 42:

When t is doubled, the equation will be...

$r=s^2/(2t)^2=\frac{s^2}{2^2 \cdot t^2}=\frac{s^2}{4t^2}\\ \\ r=0.25s^2/t^2 \; \; (or) \; \; \frac{1}{4} \cdot \frac{s^2}{t^2}$

Solution for 42:

If $t$ doubled and $s$ stays constant, $r$ is multiplied by <em><u>1/4 or 0.25</u></em>
