Answer:

-32x^2 - 48x - 10

Step-by-step explanation:

You have to distribute -8x to (5+4x) and -2 to (5+4x)

Here is how it's done.

-8x(5+4x) - 2(5+4x)

-40x - 32x^2 - 10 - 8x

Now combine the like term:

-32x^2 - 40x - 8x - 10

-32x^2 - 48x - 10

Divide 28 cans of soda into two groups so the ratio is 3 to 4
kaheart [24]
First, you add the two ratio numbers to figure out what to divide your 28 cans of soda by.

3=4=7
Next, you divide this amount into your total amount of cans of soda.

28/7=4.

This means that for each one in the ratio, there is 4 cans.  So you multiply both numbers in the ratio by 4.

3*4 = 12
4*4=16

So, your final answer is 12:16, or 12 cans of soda in one group, and 16 cans of soda in the other.

If f(x) varies directly with x and f(x) = 48 when x = 8 find the value of f(x) when x = 2
const2013 [10]
Here, f(x) = kx

k = f(x)/x
k = 48/8
k = 6

So, when x = 2, 
f(x) = 6 * 2
z = 12

In short, Your Answer would be: 12

Hope this helps!
