Answer:
-5
Step-by-step explanation:
Answer: highest number - lowest number
Step-by-step explanation:
Multiply both sides by a
(a + 4)a = -3
Regroup terms
a(a + 4) = -3
Expand
a^2 + 4a = -3
Move all terms to one side
a^a + 4a + 3 = 0
Factor a^2 + 4a + 3
(a + 1)(a + 3) = 0
Solve for a
<u>a = -1, -3</u>
Explaination:
so there is a circle which is c of center O and its diameter AB= 6cm and xy is just a straight line passing through o which is the center
so that's all you need to understand to solve this question because on this site I can't really draw a figure but I hope this explaination helps
