Answer:

4(x - 3) and x + 3(x-2) - 6 are equivalent.

Step-by-step explanation:

4(x - 3) = 4x - 12

6x - 2(x - 3) = 6x - 2x + 6 = 4x + 6

x + 3(x - 2) - 6 = x + 3x - 6 - 6 = 4x - 12

Answer:

$14\sqrt{3}-8\sqrt{5}$

Step-by-step explanation:

we have

$2\sqrt{20}-4\sqrt{45}+7\sqrt{12}$

we know that

$2\sqrt{20}=2\sqrt{2^{2}5} =2(2)\sqrt{5}=4\sqrt{5}$

$4\sqrt{45}=4\sqrt{3^{2}5} =4(3)\sqrt{5}=12\sqrt{5}$

$7\sqrt{12}=7\sqrt{2^{2}3} =7(2)\sqrt{3}=14\sqrt{3}$

substitute the values in the expression above

$4\sqrt{5}-12\sqrt{5}+14\sqrt{3}$

Combine like terms

$14\sqrt{3}-8\sqrt{5}$

You have a list of 140 'hot leads' who clicked on a link in your email. Your click rate is 4%. How many emails did you ORIGINALL

PolarNik [594]

Let

x------> number of emails originally sent

we know that

$4\%= \frac{4}{100}=0.04$

$x*0.04=140$

Solve for x

Divide by $0.04$ both sides

$x*0.04/0.04=140/0.04$

$x=140/0.04$

$x=3,500\ emails$

therefore

<u>the answer is</u>

$3,500\ emails$
