Use distributive property:
$(a+b)(c+d)+ac+ad+bc+bd$

$(2x-10)(x+3)=2x\cdot x+2x\cdot3-10\cdot x-10\cdot3\\\\=2x^2+6x-10x-30=2x^2-4x-30$

2x^2-4x-30 would be your answer

(2x−10)(x+3)
=(2x+−10)(x+3)
=(2x)(x)+(2x)(3)+(−10)(x)+(−10)(3)
=2x2+6x−10x−30
=2x2−4x−30

Connor rolled a die 6 times. A 2 occurred three times. Why isn't the theoretical probability 3/6 instead of 1/6?

Cerrena [4.2K]

2 occurred 3times

$\\ \sf\longmapsto S=6\times 3=18$

$\\ \sf\longmapsto |S|=18$

Now

$\\ \sf\longmapsto E=No\:of\:times\: 2\:occured$

$\\ \sf\longmapsto |E|=3$

we know

$\boxed{\sf P(E)=\dfrac{|E|}{|S|}}$

$\\ \sf\longmapsto P(E)=\dfrac{3}{18}$

$\\ \sf\longmapsto P(E)=\dfrac{1}{6}$

Ipatiy [6.2K]

Answer:

108 pi inches cubed

Step-by-step explanation:

The volume of a cylinder is base area times volume. Since we have our base area of 12 pi, and our height of 9, we have the are as 12* 9 = 108 pi inches cubed. Thus, the answer is D.
