We have the following expression:

2x^2y\cdot3x^5y^2

By combining similar terms, we get

2\cdot3\cdot x^2\cdot x^5\cdot y\cdot y^2

now, 2 times 3 is 6 and to add exponents, both the exponents and variables should be alike:

x^2\cdot x^5=x^{2+5}=x^7

Similarly,

y\cdot y^2=y^{1+2}=y^3

Therefore, the answer is

6x^7y^3

Which shows one way to determine the factors of x3 11x2 – 3x – 33 by grouping? x2(x 11) 3(x – 11) x2(x – 11) – 3(x – 11) x2(x 11
Aloiza [94]

The one way to determine factors of x³  + 11x² – 3x – 33  will be x^2(x+11)-3(x+11)_.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The steps involved in the factorization are;

1. For each pair of parentheses, we create a common factor.

2. We use x2 as a common factor for the first parenthesis.

3. We use common factor 3 for the second parenthesis.

x^3  + 11x^2 - 3x -33 \\\\ x^2(x+11)-3(x+11)_

We will find the final solution as x^2(x+11)-3(x+11)_.

Hence the one way to determine factors of x³  + 11x² – 3x – 33  will be x^2(x+11)-3(x+11)_.

If sine theta equals three over four, what are the values of cos θ and tan θ?
ratelena [41]

Answer:

In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus  three over root seven

Step-by-step explanation:

Given that sin ∅ =3/4 It means the ratio of the opposite side to the hypotenuse side is 3:4.

Using the Pythagoras theorem we can calculate the hypotenuse adjacent as follows.

a²+b²=c²

a²=c²-b²

a²=4²-3²

a²=16-9

a²=7

a=√7

Then Cos ∅= opposite/ adjacent

=√7/4

Then Tan ∅ = opposite/adjacent

=3/√7

In words, Cosine theta equals plus or minus square root of seven over 4,tangent theta equals plus or minus  three over root seven.

What is the answer to the problem 2/3x-40=5/6(x+36)
miss Akunina [59]

2/3x-40=5/6(x+36)

multiply each side by 6 to get rid of the fraction

6* 2/3x- 6*40=6*5/6(x+36)

4x -240 = 5(x+36)

distribute

4x-240 = 5x +180

subtract 4x from each side

-240 = x +180

subtract 180 from each side

-420 =x
