$6v(2v+3)=6v\cdot2v+6v\cdot3=12v^2+18v$

$6v\cdot2v=6\cdot2\cdot v\cdot v=12\cdot v^2=12v^2\\\\6v\cdot3=6\cdot3\cdot v=18\cdot v=18v$

6v(2v+3)
1) 6v*2v=12v^2
2) 6v*3=18v
3)put them together like this: 12v^2+18v this is your answer. If the sign had been a minus in front of the 3 your answer would have been a subtraction equation.

Simplify the following completely, show all work.<br><br>4 + ✓-27

V125BC [204]

Answer:

4+3i $\sqrt{3}$

Step-by-step explanation:

the $\sqrt{-27}$ needs to be simplified

first, I broke it down to $\sqrt{-1}$ and $\sqrt{27}$

$\sqrt{-1}$ simplifies to i ;and can be broken down to $\sqrt{9}$ and $\sqrt{3}$

$\sqrt{9}$ can be simplified further to 3

Now all you have to do is put it together

4(which you didnt have to do anything to)+ 3i( 3 from the sqrt of 9 and i from the sqrt of -1) sqrt 3( which cant be simplified further)

Solve this equation 4log√x - log 3x =log x^2

ruslelena [56]

Answer:

$x = \frac{1}{3}$

Step-by-step explanation:

*Move terms to the left and set equal to zero:

4㏒(√x) - ㏒(3x) - ㏒(x²) = 0

*simplify each term:

㏒(x²) - ㏒(3x) - ㏒(x²)

㏒(x²÷x²) -㏒(3x)

㏒(x²÷x² / 3x)

*cancel common factor x²:

㏒( $\frac{1}{3x}$ )

*rewrite to solve for x :

10⁰ = $\frac{1}{3x}$

1 = $\frac{1}{3x}$

1 · x = $\frac{1}{3x}$ · x

1x = $\frac{1}{3}$

*that would be our answer, however, the convention is to exclude the "1" in front of variables so we are left with:

x = $\frac{1}{3}$

Please help and please show work!!!

Answer:

a. 61

Step-by-step explanation:

The remainder theorem tells you the remainder of f(x)/(x -3) is equal to f(3). Using x=3 in the expression, we have ...

4x³ -2x² -10x +1

= ((4x -2)x -10)x +1

= ((4·3 -2)(3) -10)(3) +1 = (10·3 -10)(3) +1 = 20·3 +1

= 61

The remainder from division by (x -3) is 61.
