Answer:
Polynomials in one variable are algebraic expressions that consist of terms in the form axn a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial.

The expression which is equivalent to the provided expression of variable x is,
<h3>What is the equivalent expression?</h3>
Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.
The given expression in the problem is,
Let the equivalent expression of this expression is f(<em>x)</em>. Thus,
The number, with negative power, can be written in the fraction of 1 with the same but positive power or exponent. Therefore,
Solve it further as,
Hence, the expression which is equivalent to the provided expression of variable x is,

Answer:
If the first number is x and y is the second number
x = 11
y = 18
Step-by-step explanation:
If x is the first number and y is the second number then:
x + 7 = y
The sum of the two numbers is expressed as:
x + y = 29
In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation
x + y = 29
x + (x + 7) = 29
2x + 7 = 29
2x + 7 - 7 = 29 - 7
2x/2 = 22/2
That means x equals 11
Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y
11 + 7 = y
y = 18
