Select one of the factors of x3y2 + 8xy2 + 5x2 + 40.

aniked [119]

Answer:

Option a - $xy^2+5$

Step-by-step explanation:

Given : Polynomial $x^3y^2+8xy^2+5x^2+40$

To find : Select one of the factors of polynomial ?

Solution :

The polynomial $x^3y^2+8xy^2+5x^2+40$

We factor of above polynomial by taking common terms,

$xy^2(x^2+8)+5(x^2+8)$

$(xy^2+5)(x^2+8)$

From the given options,

$xy^2+5$ is one of the factors of polynomial.

Therefore, option a is correct.

Multiply 3i(−1 + 2i). What is the simplified version written in standard form, a + bi, where a and b are real numbers?

Sholpan [36]

3i (- 1 + 2i) Remove the brackets.
3i (-1) + (2i)(3i) Look at the first set of brackets around the -1
-3i + 6i^2 But i^2 = - 1[ I hope that's the way you are using it]
-3i - 6 or -6 - 3i or -3(2 - i) <<<<< answer

Boldface publishing company reported a loss of $17,225 in march. In April, the company showed a profit of $32,500. How much more

Dmitrij [34]

Answer:

Boldface publishing company had $49,725 more in April than March

Step-by-step explanation:

Step 1

Express the total amount of money Boldface had in March as shown;

Let the initial amount of money he had be;

initial=x

loss=$17,225

Net amount=initial amount-loss

Net amount in March=x-17,225

Step 2

Express the total amount of money Boldface had in April as shown;

Let the initial amount of money he had be;

initial=x

profit=$32,500

Net amount=initial amount+profit

Net amount in April=x+32,500

Step 3

To calculate how much more Boldface make in April than March;

Net amount in April-net amount in March

where;

net amount in April=x+32,500

net amount in March=x-17,225

replacing;

(x+32,500)-(x-17,225)

x+32,500-x+17,225

x-x+32,500+17,225=49,725

Boldface publishing company had $49,725 more in April than March

Which value below is included in the solution set for the inequality statement?

mixas84 [53]

You haven't provided any value, but I can tell you the solution set for the inequality.

First of all, expand both sides:

$-3x+12 > 6x-6$

Add 3x to both sides:

$12 > 9x-6$

Add 6 to both sides:

$18 > 9x$

Which is of course equivalent to

$9x < 18$

Divide both sides by 9

$x < 2$

So, every number smaller than 2 is part of the solution of this inequality.
