A180 ft long board is cut into 3 pieces. the second piece of board is twice as long as the first. the third piece of board is six times as long as the first. what is the length of the first piece of the board? a) 20ft b) 40ft c) 60ft d) 120ft

I had this math question Answer by Mimiwhatsup:

x + 2x + 6x = 180

9x = 180

x = 180/9

 = 20

A) 20ft

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
