Evaluate the following expression when x = -5 and y = 25.
kykrilka [37]

Answer:

<u>The correct answer is A. 3,120.</u>

Step-by-step explanation:

Let's solve the expression for x = -5 and y = 25, this way:

(5|x| - y³)/x

Replacing x and y, we have:

(5 * 5 - 25³)/-5 (Absolute value of -5 is 5 in the numerator but we keep it without changes in the denominator)

(25 - 15,625)/-5

-15,600/-5

3,120

<u>The correct answer is A. 3,120.</u>

What is the volume?<br> 2 mm<br> 8 mm<br> 4 mm<br> cubic millimeters
shutvik [7]

Answer:

64 mm³

Step-by-step explanation:

I am assuming there was a photo to go with this problem

However the general formula to find volume is usually V = l×w×h

  • It does not matter which measurement is which because they all get multiplied together.
  • However assigning a name to each unit of measurement we will denoted the length (l) as 2 mm, the width (w) as 8 mm, and the height (h) as 4 mm
  • Plugging these values into the formula we get: V = (2)(8)(4) = 64 mm³
