Given the question "<span>Which algebraic expression is a polynomial with a degree of 2?" and the options:
1).
2).
3).
4).
A polynomial </span><span>is
an expression consisting of variables and
coefficients, that involves only the operations of addition,
subtraction, multiplication, and non-negative integer exponents of
variables.
</span><span>The degree of a polynomial is the highest exponent of the terms of the polynomial.
For option 1: </span><span>It contains no fractional or negative exponent, hence it is a polynomial. But the highest exponent of the terms is 3, hence it is not of degree 2.
For opton 2: It contains a fractional exponent which violates the definition of a polynomial, hence, it is not a polynomial.
i.e.
For option 3: </span><span>It contains a negative exponent which violates the definition of a polynomial, hence, it is not a polynomial.
i.e.
For option 4: It contains no fractional or negative exponent, hence it is a polynomial. Also, the highest exponent of the terms is 2, hence it is of degree 2.
</span>
Therefore, <span>
s a polynomial with a degree of 2. [option 4]</span>
Answer:
71.6 °F
Step-by-step explanation:
The formula to find a Celsius temperature from Fahrenheit is: °F = (°C × 9/5) + 32. Insert 22 for °C and solve.
Answer:
56
Step-by-step explanation:
(7×6 + 10×2 -10) + (3×6 - 6×3 + 4)
(42 + 20 - 10) + (18 - 18 + 4)
(52) + (4)
52 + 4 = <u>56</u>
