Answer:

-1

Explanation:

Let the number be x.

Then the equation will be:

3(x+18) = 51

=> 3x + 54 = 51

=> 3x = 51 - 54

=> 3x = -3

=> x = -3/3

=> x = -1

So, the number you thought of is -1.

Answer:

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

Step-by-step explanation:

We need to find mistake make in work below:

$(-2x^4)^4=-16x^{16}$

The mistake here is when we have even power, the negative sign gets positive i.e $(-a)^m=a^m$ if m is even

so, in our case it would be:

$(-2x^4)^4=16x^{16}$

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

shusha [124]

Answer:

Step-by-step explanation:

You can use Pythagoras Theorem,

$8^{2} + y^{2} = (8\sqrt{6} )^{2} \\ y^{2} = (8\sqrt{6} )^{2} - 8^{2} \\y^{2} = 384 - 64\\y^{2} = 320\\y = \sqrt{320}$

∴ $y = 8\sqrt{5}$
