Answer»

<P>Step-by-step explanation:

p(x)=x+5

x+5=0

x= -5

p(x)=x-5

x-5=0

x=5

p(x)=2x+5

2x+5=0

2x= -5

x= -5/2

p(x)=3x-2

3x-2=0

3x=2

x=3/2

Answer»

$\green{\bold{\underline{\underline{Whole Numbers:-}}}}$

➡️The whole numbers are the number without fractions and it is a collection of positive integers and ZERO. It is represented as “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}

$\pink{\bold{\underline{\underline{Properties:-}}}}$

${\huge{\underbrace{\overbrace{\green{Closure Property:-}}}}}$

They can be closed under addition and multiplication, i.e., if x and y are two whole numbers then x. y or x+y is also a whole number.

${\huge{\underbrace{\overbrace{\blue{Commutative Property of Addition and Multiplication}}}}}$

The sum and PRODUCT of two whole numbers will be the same WHATEVER the order they are added or multiplied in, i.e., if x and y are two whole numbers x+y=y+x and x.y=y.x

${\huge{\underbrace{\overbrace{\white{Additive Indentity:-}}}}}$

When a whole number is added to 0, its value remains unchanged, i.e., if x is a whole number then x+0=0+x=x

${\huge{\underbrace{\overbrace{\red{Multiplicative Indentity :-}}}}}$

When a whole number is multiplied by 1, its value remains unchanged, i.e., if x is a whole number then x.1 = x = 1.x

${\huge{\underbrace{\overbrace{\purple{Associative Property:-}}}}}$

When whole numbers are being added or multiplied as a set, they can be grouped in any order, and the result will be the same, i.e. if x, y and z are whole numbers then x+(y+z)=(x+y)+z and x.(y.z)=(x.y).z

${\huge{\underbrace{\overbrace{\brown{Distributive Property:-}}}}}$

If x,y and z are three whole numbers, the distributive property of multiplication over addition is x. (y+z)=(x.y)+(x.z), similarly, the distributive property of multiplication over subtraction is x. (y-z)=(x.y)-(x.z)
