Answer:

The answer is (1/2)z - x - 3y

Step-by-step explanation:

∵ $log_{2}P=x$

∵ $log_{2}Q=y$

∵ $log_{2}R=z$

∵ $log_{2}\frac{R^{\frac{1}{2}}}{(P)(Q^{3})}$

∴ $log_{2}(R)^{\frac{1}{2}}-log_{2}P-log_{2}(Q^{3})$

∴ $\frac{1}{2}log_{2}R-log_{2}P-3log_{2}Q$

∴ $\frac{1}{2}z-x-3y$

Write the expression as a single term.<br> 3ln(x+2) - ln(x - 1)

Dafna1 [17]

Answer:

ln [(x + 2)^3 ]/(x-1)

Step-by-step explanation:

3ln(x+2) - ln(x - 1) = ln (x + 2)^3 - ln (x-1)

ln (x + 2)^3 - ln (x-1) = ln [(x + 2)^3 ]/(x-1)

Please help me solve this question

const2013 [10]

angle D = 92°

Step-by-step explanation:

Since the two figures are congruent.

angle D = angle K

20x + 12 = 25x - 8

5x = 20

x = 4

Substituting this value into angle D, we see that

angle D = 20x + 12

= 20(4) + 12

= 92°
