Question: Mystery media thanksgiving graph help or just math help?

I have a math worksheet that is from mystery media and is called “youre invited to thanksgiving dinner”. it has a bunch of points I need to graph and then end up with this pic of a turkey.
the instructions say “connect consecutive points with straight lines. start new line after word stop”
then it has things like this:
(6,9)
(6,8)
(7,9)
Stop

(-11,-7)
(-11,-10)
(-12,-7)
(-8,-5)
Stop
and so on
so what i want to know is how do i graph them
do I connect all dots or do I connect them in order like connect the dots or what?
do I have just the lines on the same line or do i have diagonals

Answer: It looks like you draw a line through all the points in one group – the few numbers before each stop, like (6,9), (6,8), and (7,9) would be a right angle.

Question: Factoring math help!!!?

My teacher assigned some review problems from previous years but really i forgot most of the math from 3 years ago. Please help

Expand (x+4) (x+6)

Expand (x-5) (x+7)

Factor by finding a GCF 2a+2b

Factor the difference of two perfect squares b^2 -25

My teacher gave 82 problems but these if i can remember and refresh my memory will help me understand to finish the whole worksheet. Thank You!

Answer: FOIL

take the first x and multiply it to everything in the other parenthasees. Then do the same with the 4. then add like terms.

so for the first, x^2 + 6x + 4x + 24

Combine like terms. x^2 + 10x + 24

same thing goes for the next one

Greatest Common Factor of 2a + 2b is 2.

Take it out and plop it on the outside. You will have 2( a + b)

Difference of squares you will eventually just look at and see.

Look at the second number and try to notice its a square of 5

Set up your parenthasees accordingly.

( b + 5) (b -5)

NOTICE that the signs are different. This is so that the middle terms cancel out and the last term is negative
