Replace x with 2+i and solve
Remember that i is the square root of -1
My phone automatically capitalizes I, so don’t be confused by that!
y=(2+I)^2 + 3(2+I) +5
y=4+4i-1+6+3i+5
y=7i+14
The sum of the interior angles is 180°
Answer:
v = 59
Step-by-step explanation:
V = ?
v + 17 - 11 = 65
Combine like terms
v + (17 - 11) = 65
v + (6) = 65
v + 6 = 65
Subtract 6 from both sides
v + 6 - 6 = 65 - 6
v = 59
