We can add only odd numbers. Let's assume that we're dealing ONLY with positive numbers. Which two odd numbers add to 20? 1+19 qualifies.
So do 3+17, 5+15, 7+13, 9+11.
Answer:
1) x= 3i, x= - 3i
2) x= +i
, x = - i
Step-by-step explanation:
1) x^2+9=0
(x+3i)(x-3i)=0
x= 3i, x=-3i
2) x^2-4=-11
x^2=-7
x= ±i
x= +i, x = - i
hope this helps!! :))

▹ Answer
<em>q = 16</em>
▹ Step-by-Step Explanation
3(q - 7) = 27
3q - 21 = 27
Add 21 to both sides:
21 + 21 = na
27 + 21 = 48
3q = 48
Divide both sides by 3:
3/3 = q
48/3 = 16
q = 16
Hope this helps!

Answer: y=−6x
Step-by-step explanation: Add -2x to both sides.
Answer:
Unable to be determined.
Step-by-step explanation:
AA postulate : 2 corresponding angles that are congruent.
SSS theorem : 3 sides of a triangle that are equal to another triangle's 3 sides.
SAS postulate: 2 sides and their included angle are congruent to another triangle's 2 sides and their included angle.
This would seem to follow the SAS postulate at first, but the angle we are provided is not the included angle of the sides. In triangle ABC, we are analyzing lines AB and AC. Their included angle is A, but we are given the measure for angle B.
Same with DEF; we analyze DE and DF, who share angle A, but we are given angle E as a measure.
Therefore, we cannot determine if the triangles are similar or not.
