Find the error & explain why it is wrong:
(3x^2y^4)^2 = 6x^4y^8

BRIANLIEST HELP!!!Find The Error & Explain Why It Is Wrong:(3x^2y^4)^2 = 6x^4y^8

Answers

Answer 1

Answer:

Step-by-step explanation:

Given expression is (3x²y⁴)²

We can rewrite the given expression as,

(3x²y⁴)² = (3)²(x²)²(y⁴)² [Every term of the the expression will be squared]

            = 9x⁴y⁸

But in the picture attached, it has been given as (6x⁴y⁸).

Therefore, in place of 6 it should be 9.

simplify 6-12b divided by 3a-6ab

Answers

Answer:

[tex]\frac{2}{a}[/tex]

Step-by-step explanation:

Given

[tex]\frac{6-12b}{3a-6ab}[/tex] ← factor both numerator and denominator

= [tex]\frac{6(1-2b)}{3a(1-2b)}[/tex] ← cancel common factor (1 - 2b) on numerator/denominator

= [tex]\frac{6}{3a}[/tex] ← cancel 6 and 3 by 3

= [tex]\frac{2}{a}[/tex]

6-12b divided by 3a-6ab is equal to 2\a

Answer:

1. 3 cookies

2. 2 cups

3. 300 calories

4. $35 per month

5. k = y/x

6. If there is no constant (k)

Step-by-step explanation:

1. The number of cookies the factory makes in one minute = (The number of cookies the factory makes in 12 minutes)/(12 minutes)

∴ The number of cookies the factory makes in one minute = 36 cookies/(12 minutes) = 3 cookies/minute

The correct answer is 3 cookies

2. The number of cups of water that leak every minute = (The number of cups of water that leak in 1/4 minute) × (The number of 1/4 minute per minute)

The number of cups of water that leak every minute = 1/2 cup per 1/4 minute × 4_1/4 minute per minute

The number of cups of water that leak every minute = 1/2  × 4 = 2

The number of cups of water that leak every minute = 2 cups

3. 5 glazed donuts contains 750 calories

The constant rate (per month) for the service = $35 per month

Which row of Pascal’s triangle would you use to expand (2x + 10y)15? row 10 row 12 row 15 row 25

Answers

Answer:

Row 15 is correct

Step-by-step explanation:

Pascal's triangle:  

                                              1                                            n = 0 , Row = 0

                                      1                 1                                  n = 1  , Row = 1

                                               :

                                          .........

                                           .......

For n = 0, Row number 1  

For n = 1,  Row number 2

For n = 2, Row number 3

We make pascal's triangle but sum of above two number, write below.  

As we can see in pascal's triangle.  

Exponent represent the number of row.  

If binomial has exponent n then nth row of pascal's triangle use.  

For

So, we have to use 15 row of pascal's triangle.  

Hence, Row 15 is correct
