Point Q is on line segment PR
alisha [4.7K]

Answer:

46

Step-by-step explanation:

PR = PQ + QR

4x - 10 =<u> x +  2x</u> + 4   {Combine like terms}

4x - 10 = 3x + 4     {Add 10 to both sides}

4x        = 3x + 4 + 10

        4x = 3x + 14              {Subtract 3x from both sides}

4x - 3x  = 14

          x = 14

PR = 4x - 10    {Plugin x = 14}

     = 4*14 - 10

     =  56 - 10

     =  46

Which expressions are equivalent to the one below ? check all that apply :)
Stella [2.4K]

Answer:

Option D and E are  equivalent to the given expression.

Step-by-step explanation:

Given : \frac{21^x}{3^x}

Solution:

\frac{21^x}{3^x}

Using identity : \frac{a^x}{b^x} = (\frac{a}{b})^x

(\frac{21}{3})^x   -- Option E

Now this can be written as  21^x = 7^x \times 3^x

Identity : a^x \times b^x = (a \cdot b)^x

\frac{7^x \times 3^x}{3^x}  -- Option D

(7)^x   -- Option D

Thus Option D and E are  equivalent to the given expression.
