Write the square of (2x+1/x)
pentagon [3]

Answer:

((2 x^2 + 1)^2)/(x^2)

Step-by-step explanation:

Simplify the following:

(2 x + 1/x)^2

Hint: | Put the fractions in 2 x + 1/x over a common denominator.

Put each term in 2 x + 1/x over the common denominator x: 2 x + 1/x = (2 x^2)/x + 1/x:

((2 x^2)/x + 1/x)^2

Hint: | Combine (2 x^2)/x + 1/x into a single fraction.

(2 x^2)/x + 1/x = (2 x^2 + 1)/x:

((2 x^2 + 1)/x)^2

Hint: | Distribute exponents over quotients in ((2 x^2 + 1)/x)^2.

Multiply each exponent in (2 x^2 + 1)/x by 2:

Answer: ((2 x^2 + 1)^2)/(x^2)

What is the measure of angle C
maw [93]

Answer:

C = 77°

Step-by-step explanation:

From the intercepted arc theorem, we can say that Angle ABC (angle B) is HALF of the arc intercepted (which is 110).

Hence, angle ABC = 55.

Now, looking at triangle ABC, we know that sum of 3 angles of a triangle is 180. We already know Angle A to be 48 and Angle B to be 55, thus Angle C is:

A + B + C = 180

48 + 55 + C = 180

103 + C = 180

C = 180 - 103

C = 77

CAN SOMEBODY HELP ME PLEASE
Mashutka [201]

Answer:

The answer to your questions are:

15.- 45 mg

16.- 25 kg

17.- 185 pounds

18.- 6 mg

Step-by-step explanation:

                                            D = (a M)  / (a + 12)

15.-

a = 4 years

M = 180

                                      D = (4 x 180) / (4 + 12)  = 720 / 16

                                      D = 45 mg

16.-                                1 pound --------------- 0.4535 kg

                                   55 pounds ------------  x

                                  x = 55 x 0.4535 / 1  

                                 x = 24.94 ≈25 kg

17.-                                1 pound --------------- 0.4535 kg

                                    x             ---------------   84.09 kg

                           x = 84.09x 1 /0.4535

                          x = 185.42 pounds  

18.-  M = 18 mg        what is 1/3 of the adult dose?

                          M = 18/3 = 6 mg
