Best ResponseYou've already chosen the best response.0b) Although the ^2b is unusual, the highest power seems to be ^3, therefore it would be a third degree equation.

Best ResponseYou've already chosen the best response.0b) there are 4 terms in the equation, and since we only label equations up to third degree, then it must be called a polynomial

Best ResponseYou've already chosen the best response.0In fact, it says its a polynomial in the question

Best ResponseYou've already chosen the best response.0A linear equation is one in which the highest power is 1 (e.g x+ y = 12) A quadratic equation is one in which the highest power is 2 (e.g x^2 + y = 12) a cubic equation is one in which the highest power is 3 (e.g. (x^3 + y^2+3 =12) a polynomial is any equation in which the power is above this

Best ResponseYou've already chosen the best response.0You asked about the descending order. I simply looked at the powers. It seems to me that the highest power was ^3 so that term came first. next ^2b (as I said this is unusual) but I put it second since we dont know what b is. Next 13ab because it is simply to the power of 1 (i.e. any number to the power of 1 is itself e.g. 13 ^1 = 13), but it had two variables a and b. and finally the last term which had only one variable (4b) so it went last.

Best ResponseYou've already chosen the best response.0@CUTEYPIE137 it is asking you to COUNT the number of terms in the expression first term: 7a^3 2nd term: 5a^2b 3rd term: 13ab 4th term: 4b therefore there are 4 terms in this expression.

Best ResponseYou've already chosen the best response.0so it would be a cubic polynomial @BPDlkeme234

Best ResponseYou've already chosen the best response.0only if the highest power was ^3 in the expression.

Best ResponseYou've already chosen the best response.0yes so in this polynomial the highest power is 3 so it is a cubic polynomial

Best ResponseYou've already chosen the best response.0Well we dont use the words polynomial if it is a cubic equation, we simply say it is a cubic equation. polynomials are equations in which the power is greater than ^3

Best ResponseYou've already chosen the best response.0you are right it is a cubic equation, if we dont know what ^2b is.

Best ResponseYou've already chosen the best response.0correct @triciaal I had mentioned previously it was an expression not an equation
