Hi!
In any quadratic in the form you have given (), the discriminant is ALWAYS
Given the quadratic formula:
<u>-------------------------------------------------------------------------------------------------------------</u>
The discriminant would be the part of the equation that is under the square root.
<u>-------------------------------------------------------------------------------------------------------------</u>
Therefore, your answer is
Answer:
20 degrees.
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees.
Therefore the third angle in this triangle
= 180 - (120 + 40)
= 180 - 160
= 20 degrees.
Answer:
Step-by-step explanation:
Distribute the negative sign
m = -4 - m +2
Add m to both sides
2m = -2
Divide by 2 on both sides
m = -1

Answer: q = 22</h3>
Work Shown:
The two angles shown are a linear pair. They add to 180
(7q-46)+(3q+6) = 180
10q-40 = 180
10q = 180+40
10q = 220
q = 220/10
q = 22
