Answer:
- yes, as written
- no, as simplified
Step-by-step explanation:
The equation can be simplified by subtracting 2x² from both sides. Doing that leaves a linear (not quadratic) equation:
y = 3x
__
A quadratic equation is a polynomial equation such that the exponents of the variables in a term have a maximum total of 2. Here, the terms 2x² match that requirement, making this a quadratic equation.
First multiply the 6 and the 5 to give you 30.
Then divided 30 by n= 15 so, 30 divided by 15= 2.
Then do 3 - 1 = 2
2 + 2 = 4

Listed below are those that are true:
The angle at vertex D is acute.
Triangle DEF is a right triangle.
We know D is acute, because a triangle has 180 internal degrees, and E is 90 degrees, so D has to be less than 90 which makes it acute.
Also, since E is 90 degrees, the triangle is a right triangle.
