Solution:

Given:

\frac{a}{b}\cdot\frac{c}{d}

Since b and d are nonzero elements, then it is the product of two rational numbers.

Multiplying two rational numbers produces another rational number.

Therefore, the product is a rational expression.

OPTION C is the correct answer.

Elena-2011 [213]

Answer:

The correct answer is: Option D) 5

Step-by-step explanation:

Given equation is:

3(x + 2) + x = 2x + 16

In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.

Putting x = 2

3(2 + 2) + 2 = 2(2) + 16\\3(4)+2 = 4+16\\12+2 = 20\\14 \neq 20

Putting x = 3

3(3 + 2) + 3 = 2(3) + 16\\3(5)+3 = 6+16\\17+3 = 22\\20 \neq 22

Putting x=4

3(4+2)+4 = 2(4)+16\\3(6)+4 = 8+16\\18+4 = 24\\22 \neq 24

Putting x = 5

3(5+2)+5 = 2(5)+16\\3(7)+5 = 10+16\\21+5 = 26\\26 = 26

The equation is true for x = 5

Hence,

The correct answer is: Option D) 5

In square ABCD, AC = 6x + 10, and BD = 10x + 2. What is the length of AC?
Oksanka [162]

Answer:

B) 22

Step-by-step explanation:

AC = BD

6x+10 = 10x+2

simplify:

subtract 6x and 2 from both sides:

4x = 8

x = 2

then:

AC = 6(2)+10 = 22

Use complete sentences to explain the process of converting a logarithmic equation to its equivalent exponential form to obtain
DanielleElmas [232]
Knowing that logarithm functions and exponential functions are inverse to each other, the procees to convert a logarithmic equation to its equivalent is to perform all the operations to set an equation of the typ:

 log _{b}x = y,

 then invert to show it equivalent form:

 x= b^{y}.

With that you have solved the equation for x.
