Answer:
b
Step-by-step explanation:
Answer : Use an app like PhotoMath
Use the FOIL method
First 4x × -2x = -8x^2
Outside 4x × -5 = -20x
Inside 3 × -2x = -6x
Last 3 × -5 = -15
-8x^2 - 20x - 6x -15 =
Combine like terms
-8x^2 -26x -15
Answer:
The distance between the two points is 8 units
Step-by-step explanation:
In the given figure
∵ The coordinates of the 2 points are (4, 5) and (4, -3)
∴ x1 = 4 and y1 = 5
∴ x2 = 4 and y2 = -3
∵ Their x-coordinates are equal
→ That means the distance between them is vertical
∴ The length of the vertical distance between two points is
the difference between the y-coordinates of the points
∵ The distance between them = Iy2 - y1I
∵ y1 = 5 and y2 = -3
∴ The distance between them = I-3 - 5I
∴ The distance between them = I-8I
→ Remember absolute value gives always positive values
∴ The distance between them = 8 units
∴ The distance between the two points is 8 units
