Answer:x=1.5
Step-by-step explanation:
Given
Two points co-ordinates are given
A=(5,-8)
B=(5,4)
let other point be C =(x,y)
Area of triangle is given by
A=20-5y+40-8x+5y-4x
A=60-8x
and A=48 square unit
48=60-8x
x=1.5
As area is independent of y therefore at x=1.5 any value of y will give area of 48 square unit
Answer:
look at this
x>2
x+1>3.
Subtract 1 from each side
x+1-1 > 3-1
There is an open circle at 2 and the lines goes to the right
20 cm
because
1 cm = 0.1 dm
so 1 dm = 10 cm
then:
2 dm = 2 * 10 cm = 20 cm
