The answer is -6
(9-15)=-6
(-8+2)=-6
(24-30)=-6
-(-6)+(-6)-(-6)= -6
13/22 It is asking the reciprocal.
A quadratic equation is in the form of ax²+bx+c. The correct option is C, All the positive solutions.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The graph of the question is given below. Since a quadratic equation has only two solutions, and this two solutions can be found by observing the graph. The coordinate at which the graph of the equation intersect the x-axis are the solution of the equation.
As it can be observed in this graph, that the graph intersect the x-axis at (1,0) and (2,0).Therefore, the solutions of the graph are 1 and 2.
Thus, both the solutions are positive or it can be concluded that all the solutions are positive.
Hence, the correct option is C, All the positive solutions.

Step-by-step explanation:
If n is pounds of nuts, and c is pounds of cereal squares, then:
n + c = 12
8n + 3c = 5.5(12)
Solve with substitution:
8n + 3(12 − n) = 5.5(12)
8n + 36 − 3n = 66
5n = 30
n = 6
c = 12 − n
c = 6
So Mia should use 6 pounds of nuts and 6 pounds of cereal squares.
Answer:
Step-by-step explanation:
By definition, equivalent expressions have the same value but they look different.
In order to solve this exercise you need to remember:
1) The multiplication of signs:
2) According to the Distributive property:
In this case you have this expresion:
Then, in order to find an equivalent expression to you need to simplify it applying the Distributive property (Remember that you must multiply each term inside the parentheses by 7)
Therefore, through this procedure you get the following equivalent expression that shows the sum of exactly two terms:
