which description must be true about these similar figures?
a)every pair of sides and angles are congruent
b)at least one pair of corresponding sides are congruent and one pair of corresponding angles are congruent
c)all corresponding angles are congruent and all corresponding side lengths are proportional

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

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
