Answer:
<u>x = 8</u>
Step-by-step explanation:
The sides are in proportion.
- 40 / 7x + 14 = 44 / 33 + 44
- 40 / 7x + 14 = 44/77 = 4/7
- 40(7) = 4(7x + 14)
- 280 = 28x + 56
- 10 = x + 2
- <u>x = 8</u>
Answer:
D
Step-by-step explanation:
Terms are separated by addition and subtraction symbols.
Polynomials consist of terms that are constant and/or variable. The variable terms must have 0 or positive exponents. Polynomials will not consist of division of variable expressions.
Examples of polynomials:
Examples of non-polynomials:
In general a polynomial when written in standard form should be comparable to:
where the 's could be zero and all the exponents,n, are positive or 0.
D is comparable since all of these are 0 except which is 1 and which is -2.
Also the other choices have either division by variable expressions and/or negative exponents on variables.

</span>D. (x + 2)2 + (y - 5)2 = 9
