Select all of the following that are quadratic equations.
deff fn [24]
What you want to do is solve all of these so that it equals to 0 on one side. The ones that are a quadratic will have x^2

x^2 - 2x = 4x + 1
x^2 - 6x - 1 = 0
Yes this is a quadratic

x^3 - 6x^2 + 8 = 0
No this is not a quadratic because the highest power of x is to the power of 3

5x - 3 = 0
No it is not a quadratic because it does not have x^2

2x^2 + 12x = 0
Yes because there's x^2

5x - 1 = 3x + 8

What is the value if x ?
dexar [7]

Answer:

x=3

Step-by-step explanation:

We have to use the fact that all angles of a triangle add up to 180 and two supplementary angles add up to 180.

First,QRS forms a line, so angle QRT and angle TRS add up to 180 or, if we call angle TRS y for the sake of having it as a variable, 45x+y=180 or y=180-45x

Now we have all three angles of the triangle, and we know all three add up to 180, so startign with our newly found angle, (180-45x)+(25x)+(57+x)=180

180-45x+25x+57+x=180

237 - 19x = 180

57 = 19x

x=3

Let me know if you need any further explanation.
