Answer:
2
Step-by-step explanation:
5-3=2 you subtract to get the answer
Perimeter is when you add all the sides together...but oh, no! There are two sides missing! So we have to find it. The horizontal like could be x and the vertical, the y. x would be 3 because one side is 7 and the other side is 4, so if we subtract them, we get 3. Same for the vertical, the y would be 3. (3+3=6)
Now we could add all sides to get the last choice, or 26 cm.
No because the more negative the temperature is , the more colder it gets
we are given
graph of a quadratic function
Quadratic function:
Those function which has degree=2
we can write it as
Since, the degree is 2
so, the shape of the curve will be parabolic
so, option-B.........Answer
Answer: 
If using complex numbers, or undefined if using all real numbers
Step-by-step explanation:
Moving -8 to the left side of the eq by adding both sides by 8=
x^2-3x+8=0
The quad formula:
a=1 b=-3 c=8
Inserting a b c values into formula: 
Simplifying: 
Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.
OR
Using complex numbers i, to replace the negative number created by subtracting 9-32.
