What is the product of (4n-5)(4n-4)

Step-by-step explanation:

To figure this out imma show you a much easier way they is called a box method and i want you to creat a box and put on the top (4n-5) know on the other side where there is a red line on the paper put (4n-4) know this box method is simple all u have to do is multiply its simple and easy if you ever get stuck on something like this you can always use the box method.

16n^2 -36n+20

Step-by-step explanation:

You have to distribute,

so multiply 4n x 4n = 16n^2

then 4n x -4 = -16n

-5 x 4n = -20n combine with -16 = -36n

-5 x -4 = 20

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
