Suppose the a mountain bike that sells for $419 is on sale for 20.5% off.

nata0808 [166]

Regular price: $419
Sale price: (1-0.205)($419) = $333.11

The bike will cost $333.11 before tax. You haven't shared the tax rate, but I can at least tell you that the cost of the bike after tax will be

(1.00 + rate as a decimal fraction)*$333.11.

Example: If the tax rate is 7.5%, then the bike will cost (1.00+0.075)*($333.11).

Answer:

B. 14x^3+39x^2+18x+20

Step-by-step explanation:

Given polynomials are:

$(7x^2+2x+4)(2x+5)\\For\ product\\(2x+5)(7x^2+2x+4)\\= 2x(7x^2+2x+4)+5(7x^2+2x+4)\\= 14x^3+4x^2+8x+35x^2+10x+20\\Combining\ alike\ terms\\= 14x^3+4x^2+35x^2+8x+10x+20\\=14x^3+39x^2+18x+20$

The product of given polynomials is:

14x^3+39x^2+18x+20

Hence, Option B is correct ..
