Compatible numbers are numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally. They are useful in estimating the sum, difference, product, or quotient.
Area = # sides * side length * apothem / 2
side length = (2 * area) / # sides * apothem
side length = 2 * 37.2 / 5 * 3.2
side length = 74.4 / 16
side length = 4.65 meters
Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0. Therefore, the equation of x-axis is y = 0. If a straight line is parallel and below to x-axis at a distance b, then its equation is y = -b.
Answer:
4
Step-by-step explanation:
A=h(sum of base)
60=h(15)
60/15=h
h=4
