Answer:

3k2 - k + 5

just add all of the variables or minus all of the variables and if u can add the non-variable numbers but if a variable has exponent add it with the same type of variable exponent so in this case 3k squared doesn't get added to anything so it just stays 3k2 and -2k gets added to k which equals -k cause -2k is bigger than k and if the bigger number is negative in any equation stays negative. Then u just add all the numbers which would be 7+-2 which would equal five.

Hope this helped

If y varies inversely as x and y = 27 when x = 12 , find x when y = - 9 .

Sergio039 [100]

Answer:

x = - 36

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 27 when x = 12, then

k = yx = 27 × 12 = 324, thus

y = $\frac{324}{x}$ ← is the equation of variation

When y = - 9, then

- 9 = $\frac{324}{x}$ ( multiply both sides by x )

- 9x = 324 ( divide both sides by - 9 )

x = - 36

Express the product of (x + 3) and (3+5) as a trinomial in simplest form.

ch4aika [34]

Answer:

The answer would be 8x + 24. And it's not a trinomial form. Why? Maybe the given is not just (3+5), it's (3x+5). So that we can get trinomial product.

Sol.

(x + 3) (3x + 5)

Each parenthesis has a binomial (two numbers)

A. Note that whenever you have two parenthesis next to each other like this, it implies factoring. So let's factor.

3x^2 + 5x + 9x + 15

We get a quartnomial (containing 4 numbers), but we're looking for a trinomial. Can we reduce this?

B. Yeah, so we reduce

3x^2 + 14x + 15

There you go, this is a trinomial.
