Answer:

The expression will be 2x^5\times x^{10}=2x^{5+10}=2x^{15}

Step-by-step explanation:

We have given the expression 2x^5\times x^{10}

We have to write this expression in kkxxnn form , here kk is real number and nn is integer

We know the property of exponent that when two function are multiplied thn their exponent are added

So 2x^5\times x^{10}=2x^{5+10}=2x^{15}

Here kk = 2 and nn = 15

What is the weight in grams of a liquid that exactly fills a 202.0 mL container if the density of the liquid is
Otrada [13]
The weight of a liquid is: 138.37 grams.

step-by-step explanation:

we are given that the volume of the container=202 ml(milliliter).
also the density of the liquid is given =0.685 grams over milliliter.
we know that the mass or weight of the liquid is given by:
weight=density×volume .
weight=(0.685×202) grams.
weight=138.37 grams.
hence, the weight of liquid that exactly fills a 202.0 milliliter container is 138.37 grams.

The volume of a cylinder varies jointly with the square of its radius and with its height: V=kr^(2)h Cylinder A has a volume of
Brrunno [24]
We have the following equation:
 V = kr ^ (2) h
 For cylinder A we have:
 251.2 = k * ((4) ^ (2)) * (5)
 Let's clear k:
 k = 251.2 / (((4) ^ (2)) * (5))
 k = 3.14
 For cylinder B we have:
 V = 3.14 * ((3) ^ (2)) * (9)
 V = 254.34 in ^ 3
 Answer:
 the volume of cylinder B is:
 V = 254.34 in ^ 3

Solve the equation. Check for extraneous solutions. <br> 2|7−7x|=2x+4
Vesna [10]

2|7 − 7x| = 2x + 4

|7 - 7x| = x + 2

7 - 7x = x + 2   or   7 - 7x = -(x + 2)

-8x = -5   or   7 - 7x = -x - 2

x = 5/8   or -6x = -9

x = 5/8   or   x = 9/6

x = 5/8   or   x = 3/2

To check for extraneous solutions, we check both solutions in the original equation.

<em>Check solution 5/8:</em>

2|7 - 7x| = 2x + 4

|7 - 7x| = x + 2

|7 - 7 * 5/8| = 5/8 + 2

|56/8 - 35/8| = 5/8 + 16/8

21/8 = 21/8

<u>Solution x = 5/8 works.</u>

<em>Check solution 3/2:</em>

2|7 - 7x| = 2x + 4

|7 - 7x| = x + 2

|7 - 7 * 3/2| = 3/2 + 2

|14/2 - 21/2| = 3/2 + 4/2

|-7/2| = 7/2

7/2 = 7/2

<u>Solution 3/2 also works.</u>

Answer: x = 5/8 or x = 3/2

What is the product of 2x+ 3 and 4x2 - 5x+ 6?
elena-s [515]

Answer:

8x³ - 25x² - 3x + 18

Step-by-step explanation:

(2x + 3)(4x²- 5x + 6)

multiply 2x by each of the three terms in the second expression to get:

8x³ - 10x² + 12x

now multiply 3 by each of the three terms in the second expression to get:

12x² - 15x + 18

Combine 'like terms': -10x² + (-15x²) = -25x²

Combine 'like terms':  12x + (-15x) = -3x

Put all terms in decreasing exponent order:

8x³ - 25x² - 3x + 18
