What are the leading coefficient, constant term and degree, if any, of the algebraic expression 7^x + 2x + 1? a. leading coefficient: 2; constant term: -1; degree: 2 c. leading coefficient: 2; constant term: 1; degree: -2 b. leading coefficient: -2; constant term: 1; degree: 2 d. none, expression is not a polynomial Please select the best answer from the choices provided A B C D I TRIED AND C IS WRONG

Step-by-step explanation:

Step 1:  Answer the question

This algebraic expression is not a polynomial therefore, none of these options match except D.  The reason why it is not a polynomial is because there is a 7^x which is not a polynomial expression.  The expression needs to be expressed as a 7x^2 + 2x + 1.  Therefore, the answer is D.

 D, none

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
