Width of the rectangle is 5 units
<u>Explanation:</u>
Let length (l) = l units
Given,
width (b) = l-3 units
Area of rectangle = 40 units
We know,
Area of rectangle = l X b
If l = 8 units then, b = 8-3 units
b = 5 units
Therefore, width of the rectangle is 5 units.
Answer:
B
Step-by-step explanation:
x² - 2xy + 3x + y² - 3y
1: Multiply the second parentheses by each term from the first parentheses
X x(x - 1 y + 3) - y x (x - 1y + 3)
2: Distribute x through parentheses
2x2 - 5x - 12 = 0.
(2x + 3)(x - 4) = 0.
2x + 3 = 0 or x - 4 = 0.
x = -3/2, or x = 4.
