Aribbon is 40 inches long. we want to cut the ribbon into pieces. each piece will be of an inch. how many pieces will we have?

40

Step-by-step explanation:

What we need here is to know how many of 1 inch are there in 40 inches

This is straightforward, what we need to do here is to imagine having to mark 1 inch length on the ribbon using a mark of a scissors.

What we will notice is that we need to make 40 marks to have exhausted the entire length of the ribbon.

This is obtained by dividing the total 40 by 1 which is 40

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
