Evaluate : 8 - 9 + (-2)
8-9= -1 (because if you take away 9 from 8, you will end up with a negative number since there isn’t enough to take away.)
-1 + -2 = -3 (this is because when you are adding two negative numbers together, you will basically just add -1 and -2 as you would normally, then you would transfer the negative sign as well to make it -3)
Finally, your answer to this question is -3.

The value of 'k' in the quadratic Equation 
having one rational solution is k is 8.
<h3>
What is a Quadratic Equation?</h3>
- Quadratic equations are the polynomial equations of degree 2 in one variable of the type
where a, b, c, ∈ R and a ≠ 0. - The standard form of a quadratic equation is
.
Here, the given equation is
By comparing the given equation with the standard form of the quadratic equation we get,
a = 4
b = k
c = 4
The given quadratic is having one rational solution, which means 
Therefore,
Therefore, the value of k is 8.

Answer:
AC = 3x + 3 (answers may vary)
Step-by-step explanation:
AB = 6x + 2
Answers may vary for this question,
Let's say that,
B = 4x + 1
So that means that,
A = 2x + 1
BC = 5x + 3
Since we chose
B = 4x + 1,
we must subtract B from BC to get C,
C = x + 2
Now we add A and C to get AC,
A = 2x + 1
C = x + 2
AC = 3x + 3
