Answer:

p=-7/2=-3.5

Step-by-step explanation:

So we have the equation:

9-4(2p-1)=41

First, let's subtract 9 from both sides:

-4(2p-1)=32

Divide both sides by -4:

2p-1=-8

Add 1 to both sides:

2p=-7

Divide both sides by 2:

p=-7/2=-3.5

And we're done!

Answer:

p=-\frac{7}{2}

Step-by-step explanation:

9 - 4(2p - 1) = 41 \\\\\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides}\\9-4\left(2p-1\right)-9=41-9\\\\Simplify\\-4\left(2p-1\right)=32\\\\\mathrm{Divide\:both\:sides\:by\:}-4\\\frac{-4\left(2p-1\right)}{-4}=\frac{32}{-4}\\\\Simplify\\2p-1=-8\\\\\mathrm{Add\:}1\mathrm{\:to\:both\:sides}\\2p-1+1=-8+1\\\\Simplify\\2p=-7\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2p}{2}=\frac{-7}{2}\\\\Simplify\\p=-\frac{7}{2}

Show that 1n^ 3 + 2n + 3n ^2 is divisible by 2 and 3 for all positive integers n.
Dmitry_Shevchenko [17]

Prove:

Using mathemetical induction:

P(n) = n^{3}+2n+3n^{2}

for n=1

P(n)  = 1^{3}+2(1)+3(1)^{2} = 6

It is divisible by 2 and 3

Now, for n=k, n > 0

P(k) = k^{3}+2k+3k^{2}

Assuming P(k) is divisible by 2 and 3:

Now, for n=k+1:

P(k+1) = (k+1)^{3}+2(k+1)+3(k+1)^{2}

P(k+1) = k^{3}+3k^{2}+3k+1+2k+2+3k^{2}+6k+3

P(k+1) = P(k)+3(k^{2}+3k+2)

Since, we assumed that P(k) is divisible by 2 and 3, therefore, P(k+1) is also

divisible by 2 and 3.

Hence, by mathematical induction, P(n) = n^{3}+2n+3n^{2} is divisible by 2 and 3 for all positive integer n.

Factor completely 2x2 − 6x − 36.
gavmur [86]
To factor out completely, we should have reached the most simplified form,
first we should take out 2.
2(x2 - 3x - 18)
then we should factor out the inside of the parenthesis,
2(x - 6)(x + 3)
And that's the most simplified and factored out form.

The final answer is then the second option, <span>2(x − 6)(x + 3)</span>
