A family is having a pool built in their backyard. If their yard is rectangular and measures 7x by 6x and the pool is circular with a radius of 2x how much of the yard will be left over after the pool is built?
38x^2
42x^2 – 4pi x^2
42x2 – 2pi x^2
38pi x^2

dw:1349333653273:dwDude, these are really similar. Try to learn from my example and do some yourself, or you'll fail your test.

Simplify the product using the distributive property. 7. (5h – 3)(3h + 7) 15h2 – 44h + 21 15h2 – 26h – 21 15h2 + 44h + 21 15h2 + 26h – 21

Is it...15h^2 + 44h +21?

Oh, I guess that's where I went wrong. Thanks. These next ones, I am having trouble with the table part to get my answer. Simplify the product using a table. ( it wont show the table. but could you help me) Give me a minute to draw it out) 8. (5h + 4)(3h + 6) 15h2 + 42h + 24 15h2 – 42h + 24 15h2 + 18h – 24 15h2 – 18h – 24

I just don't understand putting the numbers in, and making the answer out of it. Simplify the product using FOIL. 10. (4x – 4)(3x – 4) 12x2 – 28x + 16 12x2 – 4x – 16 12x2 + 4x – 16 12x2 + 28x + 16 11. A cylinder has a radius of 4x + 2 and a height of 5x + 4. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula V = pir2h for the volume of a cylinder. 80pix3 + 144pix2 + 84pix + 16pi 80pix3 – 144pix2 + 84pix + 16pi 80pix3 + 144pix2 + 84pix – 16pi 80pix3 + 144pix2 – 84pix + 16pi 12. A sphere has a radius of 4x + 4. Which polynomial in standard form best describes the total surface area of the sphere? Use the formula S = 4pir2 for the surface area of a sphere. 64pix2 + 128pix + 64pi 64pix2 – 128pix + 64pi 64pix2 + 128pix – 64pi 64pix2 – 128pix – 64pi

Okay. I didn't know what FOIL was. Can you help me with the other 2 please.
