$(s-6)(s+1)\text {and }s^2-5s-6$

Step-by-step explanation:

Given : A square has sides of length s.

According to the question,

Dimensions of new rectangles=(s-6)×(s+1)

Thus, Area of rectangle= (s-6)×(s+1)

$=s^2-6s+s-6\\\Rightarrow\ s^2-5s-6$

Thus , area of rectangle can be given by expressions:

I think it's going to make a W, but I don't understand question 3. Can someone please explain this to me?

RideAnS [48]

I thought this was a vector problem but no, this is quite easy!

You are correct; this draws the letter W.

The so-called "vector" means for you to translate the same distance. That vector goes left 3 and up 4 -- translate your point at Step 2 left 3 units and up 4 units. There you go!
