The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

$4x + 2 + 3x + 3 = 180$

$7x + 5 = 180$

$7x = 180 - 5$

$7x = 175$

$x = \dfrac{175}{7}$

$x = 25$

now, let's find Angle DCB :

$3x + 3$

$(3 \times 25) + 3$

$75 + 3$

$78 \degree$

Answer:

9 cans of tomato soup

Step-by-step explanation:

We are told that only cans of tomato soup and cans of chicken soup are put on the shelf.

Now, we are told that the ratio of the number of cans of chicken noodle soup to the total number of cans on the shelf was 8 to 17.

In fraction, this is 8/17

Now, this implies that there are 8 cans of chicken noodle soup while there are a total of 17 cans on the shelf.

Thus,

Since only cans of chicken noodles and cans of tomato soup are on the shelf, it means;

Cans of tomato soup = 17 - 8 = 9

Which of the following expresses the possible number of positive real solutions for the polynomial equation shown below?

In order to figure this out you need to use Descartes Rule. I attached a picture showing Descartes Rule. If the signs changes for when x is positive then the number of times it changes are the possible positive solution. If the sign changes when x is negative then the number of times it changes are the possible negative solutions. With that said the answer is A. View the picture I have attached for the possible + - and imaginary solutions.

Answer = A) One possible positive solution.
