Okay. So, what we do first is do the distributive property by multiply each number in the parenthesis by 3. When we do that, we get (6x + 12), because 3 * 2x is 6x and 4 * 3 is 12. Now, the numbers written out in long form is 5 + 6x + 12 + 6. 6x is in simplified form, because there is nothing that we can combine it with, but we do need to combine the whole numbers. 5 + 12 is 17, and 17 + 6 is 23. The expression in simplified form is 6x + 23. The answer is B.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer: -129

<u>Step-by-step explanation:</u>

Given the sequence {-3, 6, -12, 24, ... }, we can see that the first term (a) is -3 and the ratio (r) is $\dfrac{6}{-3} = -2$ .

Input those values into the Sum formula:

$S_n=\dfrac{a(1-r^n)}{1-r}\\\\S_7=\dfrac{-3(1-(-2)^7)}{1-(-2)}\\\\.\quad=\dfrac{-3(1-(-128))}{1+2}\\\\.\quad=\dfrac{-3(1+128)}{3}\\\\.\quad=\dfrac{-3(129)}{3}\\\\.\quad=-129$

What is the distance between these two numbers on a number line :6,4 1/4

n200080 [17]

To get the distance between

$6$ and $4\frac{1}{4}$ , we subtract $4\frac{1}{4}$ from $6$

That is,

$d=6-4\frac{1}{4}$

We change the mixed number to improper fraction now to get,

$d=6-\frac{17}{4}$

This is the same as,

$d=\frac{6}{1}-\frac{17}{4}$

We collect LCM to be 4

$=\frac{4\times6-17}{4}$

This gives us,

$=\frac{24-17}{4}$

$=\frac{7}{4}$

Convert back to mixed number to get,

$=1\frac{3}{4}$

Therefore the distance between the two numbers is $=1\frac{3}{4}$

Note that the other way round will result in negative value. That is subtracting 6 from $4\frac{1}{4}$ will give $-1\frac{3}{4}$

But since this is distance we find the absolute value and get the same result.

$d=|-1\frac{3}{4}|=1\frac{3}{4}$

Just one bacterium dividing every 20 minutes could produce nearly 5000 billion billion bacteria in one day. That is 5,000,000,00

OLEGan [10]

That is correct, however, you need to keep in mind that each bacteria created will multiply the same way the original does, so you have exponential growth
