Mathematics
1 answer:
ella [17]3 years ago
8 0

Answer:

20

Step-by-step explanation:

3x + x + 100 = 180 (sum of angles on a straight line)

4x = 180-100

4x=80

divide both sides by 4

x=20

Solve for x<br>6x²+2x-12​
dem82 [27]

Answer:

Step-by-step explanation:

Solving for x means you have to factor. First factor out the GCF of 2 to get:

2(3x^2+x-6) and now we'll factor using the regular old method of ac and then factoring by grouping. In our polynomial, a = 3, b = 1, c = -6. Therefore, a times c is 3 * -6 which is -18. We need some combinations of the factors of 18 that will add to give us 1, the b term in the middle. The factors of 18 are:

1, 18

2, 9

3, 6 and that's it. Hm...it seems that won't work, so let's throw this into the quadratic formula, going back to the original and a = 6, b = 2 and c = -12:

x=\frac{-2+/-\sqrt{2^2-4(6)(-12)} }{2(6)} and

x=\frac{-2+/-\sqrt{4+288} }{12} and

x=\frac{-2+/-\sqrt{292} }{12} and

x=\frac{-2+/-\sqrt{4*73} }{12} and

x=\frac{-2+/-2\sqrt{73} }{12} which finally simplifies to

x=\frac{-1+/-\sqrt{73} }{6} No wonder that didn't factor using the traditional method of factoring! We could have found that out by finding first the value of the discriminant, but oh well!
