Which equation can be solved using the expression
3-+_ square root of (3)^2+4(10)(2)

2(10)

Quadratic equation of the expression will be 10x²+ 3x - 2 = 0

Step-by-step explanation:

If we have a quadratic equation given as ax²+ bx + c = 0, we can find the value of x with the help of quadratic formula

Now we compare this quadratic formula with the given formula

We get the values

a = 10

b = 3

c = -2

So the quadratic equation will be 10x² + 3x - 2 = 0

Or 10x² + 3x - 2 = 0

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
