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

4, 2 or 0 positive roots
c.
d.
2 or 1 neative roots; 3 or 2 positive roots
3 or 1 negative roots; 2 or 0 positive roots
Answer:
x = 12
Step-by-step explanation:
Given
4(x - 5) = 8x + 4 - 6x ← distribute left side and simplify right side
4x - 20 = 2x + 4 ( subtract 2x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
