Answer:
-31/11
Step-by-step explanation:
To get the value they makes the fraction undefined, we shall need to equate the denominator to zero
Hence;
4x + 44x^2 + 120x
Divide through be x
4 + 44x + 120 = 0
44x = -124
x = -124/44
x = -62/22
x = -31/11
Answer:
P = 36 units
Step-by-step explanation:
<u>Pythagoras</u>
ip = √(12² + 9²)
= √(144 + 81)
= √225
= √15²
= 15 units
P = 9units + 12units + 15units = 36 units

Answer:
164
Step-by-step explanation:
(x + iy)/i = 8 + 10i
(x + iy) = (8 + 10i)(i) = 8i + 10i²
= -10 + 8i
(-10 + 8i)(-10 - 8i) = (-10)² + 8² = 164
