Answer:

19\sqrt{3x}

Step-by-step explanation:

Given expression:

10 \sqrt{3x}+4\sqrt{3x}+5\sqrt{3x}

Given answer options:

  • 9\sqrt{3x}
  • 9\sqrt{6x}
  • 19\sqrt{3x}
  • 19\sqrt{9x^3}

To simplify the given expression, factor out \sqrt{3x}:

\implies 10 \sqrt{3x}+4\sqrt{3x}+5\sqrt{3x}

\implies \sqrt{3x}(10+4+5)

Add the numbers in the parentheses:

\implies \sqrt{3x}(19)

Rearrange to standard form:

\implies 19\sqrt{3x}

Therefore, the answer is the third option.

If three times the larger of two numbers is four times the smaller and the difference between the numbers is 8, then the larger
MaRussiya [10]

Answer:

Larger number = 32

Step-by-step explanation:

Smaller number = x

Larger number = y

y - x = 8    -----------(I)

3y = 4x  ---------------(II)

3y/4 = x

Plug in x = 3y/4 in equation (I)

y - \frac{3}{4}y = 8\\\\\frac{4}{4}y - \frac{3}{4}y = 8\\\\\frac{1}{4}y = 8\\

 y = 8*4

  y = 32

Plug in y = 32 in equation (II)

3y = 4x

3*32 = 4x

4x = 3*32

x = \frac{3*32}{4}

x = 3 *8

x = 24

Brilliant_brown [7]

Answer:

x = 2

Step-by-step explanation:

logx + log(2x - 1) = log 6

x(2x - 1) = 6

2x^2 - 1x = 6

x = 2 (true) or x = -3/2 (False)
