Most flat screen TVs today are made with an aspect ratio (ratio of the length to the height) of 16:9. Xenock Electronics' top selling TV is their 28-inch model, whose viewing area has a length of 24 inches and a height of 13.5 inches. This TV costs $226.99. They have three main competitors that claim to offer a better deal per viewing area. Phil's Supercenter claims their 18-inch model, whose viewing area length is of the length of Xenock's 28-inch model, is a better deal per viewing area at $152.99. Tyler's Electronics claims their 33-inch model, whose viewing area height is 20% taller than Xenock's 28-inch model, is a better deal per viewing area at $276.99. Beltre's Superstore claims their 82-inch model, whose viewing area dimensions are 300% as large as Xenock's 28-inch model, is a better deal per viewing area at $2,079.99. List the TV's in order of best deal per viewing area. Assume all TV's have the same aspect ratio.

What are the zeros of the function y = 2x2 – 3x – 20, and why?a.the zeros are x = – 5 2 and x = 4 because in factored form, the function is y = (2x – 5)(x + 4).b.the zeros are x = – 5 2 and x = 4 because in factored form, the function is y = (2x + 5)(x – 4).c.the zeros are x = 5 2 and x = –4 because in factored form, the function is y = (2x – 5)(x + 4).d.the zeros are x = 5 2 and x = –4 because in factored form, the function is y = (2x + 5)(x – 4)?
