First you would have to distribute -5 through the first set of parentheses which would make the equation 3x-5x+30=2(10-x). Then you would have to distribute 2 through the second pair of parentheses which makes the equation 3x-5x+30=20-2x. You would then have to collect like terms which gets the equation to -2x+30=20-2x. You then cancel equal terms which makes the solution 30=20 so the statement is false.

Whst is 15 divided by 6 2/3 equals
PolarNik [594]
First you make 15 a fraction by putting it over 1.
Then you make 6 2/3 a mixed fraction.
To do this, you multiply 6 with 3 and add 2 to it. Then you put the number over 3.
We get
6 X 3 = 18
18 +2 = 20
20/3

Now, we divide 15/1 with 20/3.
When we divide it, we actually cross multiply it. Basically, we flip the fraction and multiply it.

So we get 15/1 X 3/20 = \frac{15 X 3}{1 X 20}.

We get 45/20 which can be simplified to 9/5 which can be simplified to 2  1/4.

So the answer is 9/4 or 2  1/4.

Write the formula for the volume of a square prism, V= 1/3 s^2h, in terms of h. Then find the height h of a square prism with vo
Marina CMI [18]

The formula in terms of h is h = 3V/s^2 and the value of h is 5

<h3>How to write the formula in terms of h?</h3>

The equation is given as

V = 1/3s^2h

Divide both sides of the equation by 1/3s^2

So, we have

h = 3V/s^2

The given parameters are

V = 60 and s = 6

So, we have:

h = 3 * 60/6^2

Evaluate

h = 5

Hence, the formula in terms of h is h = 3V/s^2 and the value of h is 5

Is (x-4) a factor of f(x) = x3 - 2x2 + 5x + 1? Use either the remainder theorem or the factor theorem to explain your reasoning.
Virty [35]

Answer:

(x-4) is not a factor of f(x)=x³-2x²+5x+1

Step-by-step explanation:

Uding the remainder theorem,(x-4) is a factor if the remainder is 0

Plug in x=4

(4)³-2(4)²+5(4)+1

64-32+20+1
