Question

Help needed??

Answer 1

Find the total area of all shaded rectangles. This is about Polynomials have no idea where to start

Answer 2

Step by step if possible

Answer 3

What you want to do first is identify the rectangles. I spot two. Do you?

Answer 4

I am so confused right now

Answer 5

I am confused and i do not even get my question i post

Answer 6

I completely understand

Answer 7

looks like they are all shaded

Answer 8

since they are all shaded, and since you have a square, the area is the square of the side
the length of the side is \(3x+4\) so the total area is \((3x+4)^2\)

Answer 9

ok

Answer 10

How did you get that?

Answer 11

by looking across the top and adding the two lengths. one is \(3x\) the other is \(4\) so the total length is \(3x+4\)

Answer 12

and therefore the total area is \((3x+4)^2\)

Answer 13

See the book is horrible at explaining how to do this, what does this have to do with Polynomials

Answer 14

the other answer is the area of the large square, which is \(3x\times 3x=9x^2\) plus the area of the small square which is \(4\times 4=16\) plus the area of the two reactangles, each of which is \(3x\times 4=12x\)
when you add these you get
\[9x^2+12x+12x+16=9x^2+24x+16\]

Answer 15

they are trying to get you to see by making a square, that
\[(3x+4)^2=9x^2+24x+16\]
