Arectangle has an area of x^3+5x^2+5x-2 square meters and a width of x+2 meters. find its length

A = Lw

L = ( x^3 + 5x^2 + 5x – 2)/(x+2)

Using Synthetic Division

-2 1 5 5 -2

-2 -6 2

1 3 -1 0

A = (x+2)(x^2 + 3x - 1)

L = (x^2 + 3x - 1)

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
