3 0

Answer:

Step-by-step explanation:

(-7 + 7i) - (-7 -3i) + (-7 - 8i) = -7 + 7i -7*(-1) -3i*(-i) - 7 - 8i

                  = -7 + 7i + 7 + 3i - 7 - 8i

                   = -7+ 7 - 7 + 7i +3i - 8i

Combine like terms

                  =  - 7 + 2i

How to write a polynomial in standard form
Setler79 [48]

Step-by-step explanation: Standard form is when we take a polynomial and we write it in order from the greatest degree to the smallest degree.

Let's look at an example which I provided in the image attached.

In this polynomial, I have 2 degrees, 1 degree, and 1 degree above the <em>x</em>.

This is not in the form of least to greatest so I need to write it in descending order. Our constant which in this is 27 will be last in polynomial.

So, you look at the degree of each term and then write each in term in order of degree from greatest to least (descending order).

Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise defin
ohaa [14]

Answer:

C

Step-by-step explanation:

D is missing 2 ideas.

  • An angle can be formed by a mixture of the types of figures quoted.
  • An angle has common or shared endpoint.

B: to me is unclear. A line does not have an endpoint. A ray does.

A: you need to mention that the lines are coplanar.

I think, brief though it is, C is the most complete and at the same time simplest choice.
