Answer:
None of the other answers are correct.
Step-by-step explanation:
- (Given)
- Comparing it with the general form of quadratic equation we find:
- Next, we find the value of the discriminant
- , which means the roots of the given quadratic equation are non-real or imaginary.
- Thus, last option is the correct answer.
A is correct:
Let volume v, length l, and h height.
v= (l²h)/3
v=(x²9)/3
v=3x²
6a+16
Explanation:
If there's just a variable, there's an understood 1 in front of it. So what that really says is:
7a-1a+16
So, you combine the a's. 7a minus 1a is 6a. Same as 7-1,but you have a variable stuck on the end of it.
6a+16
:^)
It remains the same. if the shape is the same then so is it's angle measure.
