3.5 because you take 7 and divide by 2 since you have to multiply you base times width to get area I think I might be wrong
The terms in descending powers of a variable are
.
Given that
Polynomial; 
<h3>We have to determine</h3>
After arranging the terms in descending powers of a variable, select the opposite of the polynomial.
<h3>According to the question</h3>
A polynomial is an expression consisting of coefficients and variables which are also known as indeterminates.
<h3>Degree of a Polynomial</h3>
The degree of a polynomial can be defined as the highest degree of a monomial within a polynomial.
The degree of the polynomial can be defined as a polynomial equation having a single variable that has the greatest exponent.
Therefore
The terms in descending powers of a variable are;

Hence, The terms in descending powers of a variable are

Answer:
b = -24
Step-by-step explanation:
25+(11/12)b=3
Subtract 25 from each side
25-25+(11/12)b=3-25
11/12 b = -22
Multiply each side by 12/11 to isolate b
12/11* 11/12 b = -22*12/11
b = -2*12
b = -24
Add the all numbers Im not sure that's the answer
