Factor: 3x4y3 – 48y3.


Solution:

3x4y3– 48y3.

= 3y3(x4 – 16).

= 3y3[(x2)2 - 42].

= 3y3(x2 + 4)(x2 - 4).

= 3y3(x2 + 4)(x2 - 22).

= 3y3(x2 + 4)(x + 2)(x -2).
whats the answer?

Answers

Answer:

The answer is [tex]\mathbf{3y^3(x^2 + 4)(x + 2)(x -2)}[/tex]

Step-by-step explanation:

We need to factor [tex]3x^4y^3 - 48y^3[/tex]

Solution:

[tex]3x^4y^3- 48y^3= 3y^3(x^4 – 16)= 3y^3[(x^2)^2 - 4^2]= 3y^3(x^2 + 4)(x^2 - 4)= 3y^3(x^2 + 4)(x^2 - 2^2)= 3y^3(x^2 + 4)(x + 2)(x -2)[/tex]

So, the factorisation of [tex]3x^4y^3 - 48y^3[/tex] is [tex]\mathbf{3y^3(x^2 + 4)(x + 2)(x -2)}[/tex]

The answer is [tex]\mathbf{3y^3(x^2 + 4)(x + 2)(x -2)}[/tex]

Answers

Both factors are negative so the result would be positive. C. Is the answer

If x=4 y=-3 and z =5 find the value of 5y +2x-z

Answers

The answer is -12.

All you have to do is substitute the variables for their values and solve.

Hope this helps!

Answer:-12

Step-by-step explanation:

So if the equation is 5y+2x-z and the substitutions are x=4     y=-3      z=5 , all you have to do is replace each variable with its given numbers. Like so

5(-3)+2(4)-5

Now what you have to do is simplify

Negative times a positive is a negative

Negative times a negative is a positive

Positive times a positive is a positive

So....

-15+8-5

-20+8

-12

This is a simple substitution problem. Remember the basics of negatives and positives! Than you will be just fine! :D

Which set of transformations would prove triangle GFE ~ triangle GHI?

Answers

Answer:

Dilation of 1/2 and then a reflection over y=2

Answer:

reflect GHI over x= -2, and dilatate G'H'I' by a scale factor of 2 from point G

Step-by-step explanation:

EFG is turned the other way, meaning that GHI was flipped. because EFG is bigger, and having a scale factor that's a whole number means it gets bigger, then this answer is correct because its both bigger and flipped in the picture.

round 967 to ? round to the nearest hundred

Answers

Answer:

967 is 1000.

Step-by-step explanation:

0-4 stays the same, 5-9 goes up one. The number after the one that needs to be rounded is the one you should worry about. For 967, 6 is the number after the primary number that needs to be rounded to the hundred. Since 6 is between 5-9, 6 goes up one and changes 967 into 1000.

The answer is 1,000

Always round up when it’s 5 and over

The Daily Info charges a fee of plus per week to run an ad. The People's Paper charges per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper.

Answers

Complete question :

The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper

Answer:

650 + 80w < 145w

Step-by-step explanation:

Given that :

Number of weeks ad will run = w

Daily Info total cost :

650 + 80w

The People's Paper total cost:

145w

Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';

Daily Info total cost < people's choice

650 + 80w < 145w

650 < 145w - 80w

650 < 65w

650/65 < 65w / 65

10 < w

w > 10
