Answer:

The formula to get the circumference of a circle is $C=2*\pi * r$ but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this $C=d*\pi$ .

We can then input the value and we get that $C=3*\pi$ which then just narrows down to $C=9.425$ .

What is the simplified form of the following expression?

ziro4ka [17]

For this case we must simplify the following expression: $7 (\sqrt [3] {2x}) - 3 (\sqrt [3] {16x}) - 3 (\sqrt [3] {8x})$

We rewrite:

$16x = 2 ^ 3 * 2x\\8x = 2 ^ 3 * x$

We rewrite the expression:

$7 (\sqrt [3] {2x}) - 3 (\sqrt [3] {2 ^ 3 * 2x}) - 3 (\sqrt [3] {2 ^ 3 * x}) =$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

Then, taking the terms of the radical:

$7 (\sqrt [3] {2x}) - 3 (2 \sqrt [3] {2x}) - 3 (2 \sqrt [3] {x}) =\\7 \sqrt [3] {2x} -6 \sqrt [3] {2x} -6 \sqrt [3] {x} =$

We add similar terms:

$\sqrt [3] {2x} -6 \sqrt [3] {x}$

Answer:

x=61

2x+3 = 125

x-6 = 55

Step-by-step explanation:

The two angles shown form a straight line so they add to 180

2x+3 + x-6 = 180

Combine line terms

3x-3 =180

Add 3 to each side

3x-3+3 =180+3

3x=183

Divide each side by 3

3x/3 =183/3

x =61

The angle on the left is 2x+3

2x+3 = 2*61+3 = 122+3 = 125

The angle on the right is x-6 = 61-6 = 55

The positive multiples of a whole number were listed from least to greatest. If the third multiple was 42, what was the 5th mult

Nuetrik [128]

Answer:

$70$

Step-by-step explanation:

If the third multiple of the whole number is $42$ . This means that $42$ is completely divisible by the number $3$ .

$\dfrac{42}{3}=14$

So, the whole number is $14$ .

The fifth multiple would mean the product of $14$ and $5$

$14\times 5=70$

The fifth multiple of the whole number is $70$ .
