Abook has a length of (b+2) inches and a width of b inches. write a simplified expression for the perimiter of the book.

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

m∠a is 90°

m∠b is 40°
