Equation of parabola is .
<u>Step-by-step explanation:</u>
The vertex form of the parabola is given as,
where (h,k) is the vertex of the parabola.
If the parabola must be symmetric about x = -10 then the axis of symmetry must be x = -10.
To execute this, h should be -10, and it was plugged in the vertex form of the parabola, a and k may be any real number.
So the equation can be written as,
<u />
Number 15 is c and number 16 is a
Note: Since you have not added the expression, so I am taking a sample expression which anyways would help you clear your concept regarding factors.
Answer:
Assuming the expression
- The expression consists of two terms. i.e. and .
- and are factors of the expression .
Step-by-step explanation:
Lets us consider an expression
Observe that and are connected by addition. Thus, are terms. So, The expression consists of two terms. and .
Next, let's have some discussion about factors in a mathematical expression.
Factors are said to be the parts of the expression which are connected by multiplication.
Now lets solve the example to determine the factors
∵
Therefore, and are factors of the expression .
The answer is 17 hope it helps
