Answer:

<h3>Find the solution below</h3>

Step-by-step explanation:

The expression is incomplete. Let say the expression is 4 (-2u + 7) = 44

Given the expression

4 (-2u + 7) = 44

Step 1: Open the bracket by distributing 4 over -2u and 7

4 (-2u + 7)= 44

4(-2u) + 4(7) = 44 (distributive property)

-8u + 28 = 44

Step 2: Subtract 28 from both sides

-8u + 28 - 28 = 44 - 28  (subtraction property of equality)

-8u  = 16

Step 3: Divide both sides by -8

-8u/-8 = 16/-8 (division property)

u = -2

The hour hand of a clock moves −30° every hour. How many degrees does it move in 2 1/5 hours? The hour hand of a clock moves ___
never [62]

The number of degrees does it move in 2 1/5 hours is -66°.

<h3>How to calculate the number of degrees?</h3>

From the information given, it was illustrated that the hour hand of a clock moves −30° every hour.

Therefore, to calculate the degree for a number of hours, we simply have to multiply.

In this case, to get the degree for 2 1/5 hours will be:

= Degree every hour × Number of hours

= -30° × 2 1/5

= -30° × 2.2

= -66°

How do extraneous solutions arise from radical equations?
AnnyKZ [126]
You get extraneous solutions anytime the radical becomes undefined under the set of real numbers.  for example \sqrt{-1} does not exsist since the radical cannot be used on a negative number
