Answer:
4x+ 4
Step-by-step explanation:
The answer is the 3rd option which is -24
By using the distance formula which is attached
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
2x - 3(x - 4) = 11
2x - 3x + 12 = 11
-1x = -1, x = 1
y = 1 - 4 = -3, y = -3
Solution: x = 1, y = -3
