The area of a rectangle is 4.9 square units. the length is 2.5 units and the width is y units.

what is the value of y?

y = 1.96

y = 2.4

y = 7.4

y = 12.15

For the quadratic function [tex]y=(x+4)^2-1[/tex] , do the following: a) rewrite the function in the standard form, b) rewrite the function in intercept form, c) find the vertex, d) find the y-intercept, e) find the x-intercepts.
