Question

find the area of the rectangle if the length 2x^3 and the width is 7x^3

Answer 1

what is the formula for rectangle area ?

Answer 2

A=lw

Answer 3

good so we need to do
Area = (7x^3) * (2x^3)

Answer 4

(ax^n) * (bx^m) = abx^(n+m)
can you do it now ?

Answer 5

The common equation for the area of a rectangle is Area = Length x Width, right?
So, you have length and width. Area = (2x^3) * (7x^3). From here it's just algebraic multiplication. Simply multiply their coefficients (the 2 and the 7) and ADD their powers (3+3). Hope that helps.

Answer 6

no

Answer 7

is it 14x^6

Answer 8

using : (ax^n) * (bx^m) = abx^(n+m)
we get: A = (7x^3) * (2x^3) = (2*7*x^(3+3))

Answer 9

yes

Answer 10

awesome thanks :o)
