One of Marianna's homework problems was to solve the equation below.

Mathematics
1 answer:
Strike441 [17]4 years ago
3 0

Answer:

<h2>Marianna is incorrect because x2</h2><h2>2x13 can be factored into two binomials</h2>

Step-by-step explanation:

ax^2+bx+c = 0

x=−1+√14 or x=−1−√14

discriminant=56

completing square x=−1+√14 or x=−1−√14

Now, we can solve each term for  

x=-2 she is incorrect

x(x+2)=0

Now, we can solve each term for  

0:  

x=0

- no other work needed,

and

x+2=0

x+2-2=0-2

x+0=-2

<u>x=-2</u>

Please put the explanation!
BaLLatris [955]

Answer:

60

Step-by-step explanation:

In order to get this answer, we must know that a triangle's angles add up to exactly 180. Also, Angles that intersect will have congruent, opposite sides. The last thing is that a line is = 180 degrees. So, the triangle with the 94 and the 142, you can use that. the angle next to the 142 is going to be 180-142 which is 38 and since the other angle is opposite 94, as well. when you add those up u get 132 and 180-132= 48 which is the missing angle for the far right triangle. then, you get the opposite of that angle, put that in the other triangle, do the same with the 72, and add those up to get 120 and since a triagle adds up to 180, 180-120 = 60. So, 60 is your missing angle. Cheers

If the measure of ZB is 40°, what measures can ZA and
lubasha [3.4K]

Answer: 30° and 110°

55° and 85°

70° and 70°

The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:

= 180° - 40°

= 140°

Therefore,

30° + 110° = 140°

55° + 85° = 140°

70° + 70° = 140°
