Write an algebraic expression for the following phrase 3 more than twice a number

2 x + 3

Step-by-step explanation:

3 more than twice a number

we have to write above equation in the form of algebraic expression

An algebraic expression is a combination of constant or variables by using suitable operators.

Let the Number be x

Twice a number i.e, we have to multiply the number by 2= 2 x

3 more i.e, we have to add 3 to above algebraic expression = 2 x+ 3

Hence, the above algebraic expression can be written as 2 x +3

Hence, the correct answer is 2 x + 3

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
