What is the area of the parallelogram represented by the vertices A(-6, -1), B(-2, -1), C(-1, -4) and D(-5, -4)?
kramer

Answer: 12 units²

Step-by-step explanation:

To find the area of a parallelogram, we use the formula A=l×w. To find the length and width, let's graph out the parallelogram to get a better view. Let's refer to the picture attached to see what the graph looks like. The length is 4 units while the width is 3 units. Therefore we multiply.

A=4×3=12 units²

Now, we know the area is 12 units².

Sandy charges each family that she babysits a flat fee of 10$ for the night and an extra 5$ per child Kimmi charges 25$ per nigh
Finger [1]
I am not going to answer each but here is a general answer.
y is total price and x is number of kids
Sandy's equation would be y= 10+5x
Kimmi's equation would be y= 25

For them to equal we would have 25=10+5x
Simplify 
5x=15
x=3
So for them to be equal, Sandy should have 3 kids.

So if someone has 5 children then he should choose Kimmi

Factorise mx+cx+my+cy<br> With steps!!!<br> x=algebra x
avanturin [10]

Step-by-step explanation:

Hey there!

While factorising you remember to make it take common in most of the expression.

Here;

=mx+cx+my+cy

Take common 'x' in "mx+cx" and 'y' in my + cy.

= x(m+c) + y(m+c)

Now, "(m+c)" common again.

= (m+c) (x+y)

Therefore the factorized form of the expression in (m+c)(x+y).

<u>Hope it helps</u><u>.</u><u>.</u><u>.</u>
