Using the distance formula:
Distance = √((x2-x1)^2 + (y2-y1)^2)
Distance = √((5-2)^2 + (-8 - -4)^2
Distance = √(3^2 + -4^2)
Distance = √(9 +16)
Distance = √25
Distance = 5
It is in simplest form. Decimal form is 14.4
when you subtract a negative number from any platitude number the equation changes to addition so you would add the value of the negative number to 1.
Answer:
4x + 16
Step-by-step explanation:
Area of a triangle is:
A = ½ bh
Here, b = x+4 and h = 8:
A = ½ (x + 4) (8)
A = 4x + 16
