Answer:

$6x^{2} +9x -4x+6\\$

Step-by-step explanation:

First you take 3x times 2x since its the first of both equations, which will give you 6x squared.

Then take the outer ones of both problems which is 3x times 3 which is 9x.

Then the inner, -2 times 2x which is -4x

Then the last of both individual problems which is -2 times -3 which is positive 6.

Justine bought a pair of boots for $76.68 and paid 13% sales tax. What was the price of these boots including tax?

MArishka [77]

Answer: $86.65

Step-by-step explanation:

First, find how much Justine paid in tax. To do this, first convert 13% to a decimal by dividing by 100. This gets a tax rate of 0.13. Now, multiply the price of the boots by the tax rate. 76.68*0.13 = 9.9684. Round to the nearest cent to get $9.97.

Now, add the amount paid in tax to the price of the boots. 76.68+9.97 = $86.65.

Put the steps in correct order to prove that if x is irrational, then 1/x is irrational using contraposition.

SOVA2 [1]

Answer:

The correct order is:

Step-by-step explanation:

First, let's write 1/x in a convenient way for us:

a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.

Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:

c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.

Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:

d) Observe that x is the quotient of two integers with the denominator nonzero.

And that is the definition of rational, then we end with:

b) Hence x is rational.

Which is what we wanted to get.

Use the change of base formula to evaluate log3(73).

Marrrta [24]

The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,

$log_{a}x = \frac{ log_{b}x }{log_{b}a }$

where a≠1 and b≠1

Assigning the base to be 7,

$log_{3}73 = \frac{ log_{7}73 }{log_{7}3 }=3.9$

I hope I was able to answer your question. Have a good day.
