Question

The area of a rectangle knitted blanket is 15x^2-14x-8. What are the possible dimensions of the blanket. Use factoring.

Answer 1

ok

Answer 2

I think i got it

Answer 3

is this the answer (5x+2)(3x−4)

Answer 4

Answer 5

yeah thats correct factoring
but its not the answer exactly

we need to tell the dimensions(the length and the breadth) of the rectangle

we know that area of rectangle is given by this-

Area=length x breadth

and the area given is this-
\(15x^2-14x-8\)
and we know that

\(15x^2-14x-8=(5x+2)(3x-4)\)

compare this^ with this-> \(area=(length)(breadth)\)

compare these two equations and try to deduce the length and breadth

Answer 7

Check out qwerty's new album. 2017

Answer 8

yeah this factoring is also correct :)

\(\large \color{red}{area}=(\color{gold}{length})(\color{blue}{breadth})\)

\(\large \color{red}{15x^2-8x-4}=(\color{gold}{5x+2})(\color{blue}{3x-4})\)

comparing the similar terms-

\(\large \color{red}{area}=\color{red}{15x^2-8x-4}\)

\(\color{gold}{length}=\color{gold}{5x+2}\)

\(\color{blue}{breadth}=\color{blue}{3x-4}\)

Answer 9

okay =]where are you getting confused tho?

Answer 10

medal just cuz :D
