The length of a rectangle is 6 meters longer than the width. the perimeter is 42 meters. what is the width?

perimiter=2(L+W)=42

42=2(L+W)

divide by 2

21=L+W

length is 6 longer than width

L=6+W

subsituet

21=L+W

21=(6+W)+W

21=6+2W

minus 6 both sides

15=2W

7.5=W

width is 7.5 meters

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
