True. Integers are whole numbers both positive and negative. Natural numbers are only whole positive numbers. So it is true whenever you are dealing with positive integers and it is false when you are dealing with negative integers.
F=1.8C+32
We are given C=-20 degrees
plugging this value in the given equation
F=1.8(-20)+32
F=-36+32=-4
F=-4 degree fahrenheit
No, the sum of the lengths of any two sides must be greater than the length of the third side
(3x-5)(2x-7)
6x^2 - 21 x -10x +35
6x^2 -31x +35
The first one
30/3=10
10*2=20
the volume of the smaller figure is 20 cubic cm
