the length of a rectangle is 4 units more than it's width. The area of a rectangle is 25 more than 4 times the width. What is the width of the rectangle​

solution,

let width of the rectangle be x then,

length(l)=4x

Area(A)=25l

now,

area of rectangle = 4x×x

Step-by-step explanation:

in 2nd step one x cancel another in opposite side of =

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
