-3*10= -30 to the 4th power is 810,000
10 to the -3 power is -1000 * 2 is -2000
810,000 * -2000 = -1,620,000,000
Although theoretically there are infinite lines in space and in a plane, too, at least three non collinear points are necessary to define a plane. Two intersecting lines will therefore be necessary to define it (two points create a line); these intersecting lines are the ones to help define coordinates (x,y).
Answer:
33 tiles
Step-by-step explanation:
Given

Required
Determine the number of tiles in 11 points
Represent this with x. So, we have:


Cross Multiply

Multiply through by 3

1 meter is 100 centimeters
10 millimeters is 1 centimeter
400 millimeters is 40 centimeters
100 + 85 + 40 = 225
225 centimeters
