Answer 2
Answer:

Answer:

{ \rm{( {2x}^(2) - {x}^(3) - 18 {x}^(2) - 7) / (x + 2) }}

• now, (x + 2) is the factor.

• let's find the value of xfrom the factor:

{ \rm{x + 2 = 0}} \n { \underline{ \rm{ \: \: x = - 2 \: \: }}}

• let's substitute for xinto the quotient:

{ \rm{f(x) = {2x}^(2) - {x}^(3) - {18x}^(2) - 7 }} \n \n { \rm{f( - 2) = 2 {( - 2)}^(2) - {( - 2)}^(3) - 18 {( - 2)}^(2) - 7 }} \n \n { \rm{f( - 2) = 8 +8 - 72 - 7}} \n \n { \boxed{ \boxed{ \pmb{answer \: \dashrightarrow \: \: {}^( - ) 63 \: \: }}}}

Which of the following does not have a sum of 6?2 + 4
8 + (-2)
-4 + (-2)
-2 + 8

Answers

2 + 4 = 6

8 + (-2) = 6

-4 + (-2) = -6

-2 + 8 = 6

Since the third option equals -6, the answer would be: -4 + (-2).

A 10 inch diameter pumpkin pie is cut into 6 equal servings. What is the area of the top of each piece of pie?

Answers

The area (A) of the whole circle is calculated through the formula, A = πd² / 4. Substituting the given diameter, A = π(10 in)² / 4 = 25π in². The area of the top of each piece is 1/6 of the this area. Thus, the answer is approximately 4.17 in².

What is the answer to this problem?

Answers

The slope of a line is (dy)/(dx)

where d is the difference and y and x are the values.

In this case, the difference in y is 10 and the difference in x is 0

And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the y axis.
