Answer:
The correct answer is option C. x² - 4
Step-by-step explanation:
Area of rectangle = Length * Width
It is given that ,
The length of a side of a rectangle is 2 units less than a number, and the width is 4 units more than the length.
Let 'x' be the number
Length of rectangle = x - 2
Width = Length + 4 = x - 2 + 4 = x + 2
<u>To find the area of rectangle</u>
Area = Length * Width
Area = (x - 2)*(x + 2) = x² - 4
Therefore option C. x² - 4 is the correct answer

Answer : The correct option is, (a) 19°
Step-by-step explanation:
Opposite angles : These are the angles in which a pair of parallel lines are cut by tranversal then the two angles share the same corner.
Opposite angles are also congruent angles, that means they are equal.
As we know that the opposite angles are equal.
And, (3x - 8)° & (2x + 1)° are alternate interior angles.
Thus, the expression will be:
(3x - 8) = (2x + 1)
3x - 8 = 2x + 1
3x - 2x = 8 + 1
x = 9
(3x - 8)° & (2x + 1)°
(3(9) - 8)° & (2(9) + 1)°
19° & 19°
Therefore, the measures of the marked angles is, 19°

Answer:
Step-by-step explanation:
Let's look at this in this perspective. There are 60 minutes in 1 hour. What I would do first is get rid of the 39 minutes at the end of 8:39. Now you have 8:00. Count until you get to 7 AM. 9, 10, 11, 12, 1, 2, 3, 4, 5, 6, 7. That's 11 hours from 8 PM to 7 AM. 60 x 11 = 660. Now, there are 11 minutes more on that 7-o clock and the 39 minutes we got rid of in the beginning. 11 + 39 = 40. 660 + 40 = 700.
Answer: Kenny's energy was off for 700 minutes, or 11 hours and 40 minutes.
