Answer:

  • 3\sqrt{6}\times \:2\sqrt{3}=18\sqrt{2}
  • 5\sqrt{12}+3\sqrt{3}=13\sqrt{3}

Step-by-step explanation:

                                                        1)

Given the expression

3\sqrt{6}\:\times \:2\sqrt{3}

\mathrm{Factor\:integer\:}6=3\times \:2

=3\sqrt{3\times \:2}\times \:2\sqrt{3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}

=3\sqrt{3}\sqrt{2}\times \:2\sqrt{3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt{a}\sqrt{a}=a

=3\times \:2\times \:3\sqrt{2}

=18\sqrt{2}

Thus,

3\sqrt{6}\times \:2\sqrt{3}=18\sqrt{2}

                                                        2)

Given the expression

5\sqrt{12}+3\sqrt{3}

\:=\:5\sqrt{\left(4\right)\left(3\right)}+3\sqrt{3}

=\:5\times 2\sqrt{\left(3\right)}+3\sqrt{3}

=10\sqrt{3}+3\sqrt{3}

\mathrm{Add\:similar\:elements:}\:10\sqrt{3}+3\sqrt{3}=13\sqrt{3}

=13\sqrt{3}

Thus,

5\sqrt{12}+3\sqrt{3}=13\sqrt{3}

Organize your data and find the rate of change.
LuckyWell [14K]
A .E is 7 inches for the left arm
E is 8 1/2 inches for the left foot
the inputs look like the length of the arm (ie x) the outputs are the length of the foot 
<span>rate of change=<span>change in y change in x</span></span> use the data you gathered or this equation they give you  = 0.860 •  + 3.302


B. find the difference in y, then the difference in x, then divide (y over x) to get the slope
8-7/7 1/2-6 1/2 = 1/1 =1

C.you plug in any (x,y) point you used to find the slope
Solve for B
y = mx+b y = 1*x + b 7.5 = 1*8 + b b =
7.5 - 8 = -0.5
<span>y = x - 0.5</span>

Hope this helps
