Answer:

$\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7$

Step-by-step explanation:

Given

$\frac{3x^6}{6x^{-1}}$

Required

Solve

In laws of indices, we have:

$\frac{x^m}{x^n} = x^{m-n}$

So, the expression becomes:

$\frac{3x^{6 - (-1)}}{6}$

$\frac{3x^{6 +1}}{6}$

$\frac{3x^7}{6}$

Divide 3 and 6 by 3

$\frac{1x^7}{2}$

$\frac{x^7}{2}$

This can be rewritten as:

$\frac{1}{2}x^7$

Hence:

$\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7$

The square of a number exceeds that number by 12. What are the two possible solutions?

laiz [17]

Answer:

The correct answer is option C.

Step-by-step explanation:

Let the number be x.

The square of a number exceeds that number by 12 .Mathematically can be written as:

$x^2-x=12$

$x^2-x-12=0$

Using middle term splitting to factorize the expression:

$x^2-4x+3x-12=0$

$x(x-4)+(3)(x-4)=0$

$(x+3)(x-4)=0$

The two possible solutions are :

1) (x+3)=0

x = -3

2) (x-4)=0

x = 4

Misty must pack 365 candles into 15 boxes. Each box must contain an equal number of candles. How many candles does she have left

olganol [36]

The answer is 5 because you can fit 365 into 15 24 times and then that would equal 360 and then you have 5 left over.

15x24=360 365
