Question

Simplify the product using FOIL. (3x-4)(6x-2) @GretaKnows

Answer 1

okay foil stands for:
First terms
Outer terms
Inner terms
Last terms

Answer 2

18x^2+18-8?

Answer 3

so mulitply the first terms together. 3x and 6x= 18x^2
now the outer 3x and -2 = -6x
Inner -24x
last -4 and -2 = 8
18x^2-30x+8

Answer 4

thanks

Answer 5

theres more

Answer 6

sure! okay ill help if you want me to!

Answer 7

A cylinder has a radius of 2x + 3 and a height of 6x + 1. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula v= pie r^2 for the volume of a cylinder.

Answer 8

okay so this one is a little more complicated. you have to do (2x+3)(2x+3). what do you think that is?

Answer 9

a 12piex^2+20piex+3pie

Answer 10

no what is (2x+3)(2x+3)?

Answer 11

4x+9?

Answer 12

no 4x^2+12x+9

Answer 13

now you have to mulitply by the height. (4x^2+12x+9)(6x+1)

Answer 14

24pie^3+76piex^2+66piex+9pie
