5x^4-7(-x)
Would the simplified version of this be 5x^4+7x?

5x⁴ + 7x or x(5x³ + 7 )

Step-by-step explanation:

Given expression:

        5x⁴ - 7(-x )

To simplify this expression, we have to follow the order of operation PEMDAS;

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction

  5x⁴ - 7(-x ) = 5x⁴ + 7x

               Since x is common to both terms;

                = x(5x³ + 7 )

So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )

5/20 so 25%

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
