Which expression is equivalent to 3(4m - 2) - 2(m + 5)
tangare [24]

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6  -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.

How do you write in exponential form?
skelet666 [1.2K]
Exponential form is an easier way to write a number product of many factors. The exponent tells us how many times the base is used as a factor.
Example: Write 2 x 2 x 2 x 2 x 2 using exponents.

My math problem is 3n(squared) - 28 = -17n I have to factor this! So i would move the 17 over and make it 3n(squared) +17n - 28
wel
It's easier I think to take it and go "what can I add together than makes 17, yet multiplies to 28"
although, I don't think this is a perfect square, either

(x+7)(3x-4) = 0

heres the factored form, but I couldn't even begin to say how I got it, all I know is that it works

If f(x) varies directly with x and f(x) = 40 when x = 8, find the value of f(x) when x = 2.
Mars2501 [29]

For this case we have a direct variation of the form:

f (x) = kx

Where "k" is the constant of proportionality. To find it, we use the following data:

f (x) = 40\ and\ x = 8

Substituting:

40 = k * 8

Clearing the value of k:

k = \frac {40} {8}\\k = 5

Thus, the direct variation is given by:

f (x) = 5x

Forx = 2 we have:

f (2) = 5 * 2\\f (2) = 10

Answer:

The value of the direct variation for x = 2is: f (2) = 10
