15 + 6(x + 1)

First, expand to get rid of parentheses.
$15 + 6x + 6$
Second, simplify. Keep your 6x and add 15 + 6.
$6x + 21$

Answer: 6x + 21

First you use the distrbutive property and multiply 6 by x and 6 by 1 then you get 15 + 6x + 6 now add 15 and 6 together and you get 21 + 6x as your answer

You are comparing cell phones. The old model is 7/8 of an inch thick. The new model is 3/5 of an inch thick. How much thinner is

Sloan [31]

The new model is 11/40 of an inch thinner than the old model.

In order to do this, we need to subtract the new model from the old model.

7/8 - 3/5

In order to complete this, we will need common denominators.

35/40 - 24/40

Then simply complete the operation.

11/40

If f(g(x)) = 4(x^6 + 9)^2 and g(x)=x^6+9, find f(x). f(x) help (formulas)

labwork [276]

Answer:

The function is $f(x)=4(x)^2$

Step-by-step explanation:

Given : If $f(g(x))= 4(x^6 + 9)^2$ and $g(x)=x^6+9$

To find : The function f(x) ?

Solution :

$f(g(x))=(fog)(x)$ where the function g is inside of the function f.

We have given,

$f(g(x))= 4(x^6 + 9)^2$

The function $g(x)=x^6+9$

Substitute in equation,

$f(g(x))= 4(g(x))^2$

We know that g(x) is placed over x in the function,

$f(x)= 4(x)^2$

Therefore, The function is $f(x)=4(x)^2$

How many tenths are there in four fifths?

sleet_krkn [62]

So to find how many tenths, or 1/10's, there are in four fifths, or 4/5, divide 4/5 by 1/10.

$\frac{4}{5} \div \frac{1}{10}$

Now, remember that <u>dividing by a number is equivalent to multiplying by its reciprocal</u>. To find the reciprocal, just flip the numerator and denominator around. In this case, 1/10 would become 10/1. Flip 1/10 to its reciprocal, change the sign to multiplication, and multiply numerators with numerators and denominators with denominators:

$\frac{4}{5}\times \frac{10}{1}=\frac{40}{5}=8$

<u>In short, there are 8 tenths in four fifths.</u>
