The correct answer for this question is this one: "(80 + 50i) / 89" or <span>quantity of negative 80 plus 50 i over 89 
</span>
The expression is <span><span>10 over quantity of 8 minus 5 i. 
</span>10 / (8 - 5i)

= 10 / (8 - 5i) * (8 + 5i) / (8 + 5i)
= 10 * (8 + 5i) / (64 +25)
= (80 + 50i) / 89

What is the maximum number of terms a fourth-degree polynomial function in standard form can have?
horrorfan [7]
A polynomial of four terms is sometimes called a quadrinomial, but there's really no need for such words.
Likewise, what is a 4th degree polynomial? Fourth degree polynomials are also known as quartic polynomials. Quartics have these characteristics: Zero to four roots. One, two or three extrema. Zero, one or two inflection points.
The degree of a polynomial is the highest of the degrees of the polynomial's monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer.
Zero Polynomial. The constant polynomial. whose coefficients are all equal to 0. The corresponding polynomial function is the constant function with value 0, also called the zero map. The zero polynomial is the additive identity of the additive group of polynomials.

Can someone help with this math problem? 3 (x+6) = 27
Ainat [17]

Answer:

x = 3

Step-by-step explanation:

Use distributive property: a(b +c) =(a*b) + (a*c)

3(x + 6) = 27

3*x + 3*6 = 27

3x + 18  = 27 {Subtract 18 from both sides}

3x + 18 -18 = 27 - 18

         3x    = 9  {Divide both sides by 3}

        3x/3 = 9/3

x = 3

Hey can you please help me posted picture of question
True [87]
Ways to spot if an expression is not a polynomial:
1) If there is a negative exponent
2) If there is division by a variable
3) If the power is something other than a non-negative integer

If any of these conditions exist, the expression will not be a polynomial. Now consider the options. Option A has negative exponent, Option B involves division by a variable and Option D has a exponent which is not a number.

So, from the given options, option C is the only polynomial
