Answer:
Step-by-step explanation:
We know i×i=i^2 which has value of -1.
We will multiply numerator and denominator by i so the denominator will no longer contain imaginary part(s).
Also multiplying by i/i does not change the value of the fraction because i/i=1.
Numerator × i gives (-5+i)i=-5i+i^2=-5i-1
=-1-5i.
Denominator × i gives (2i)i=2i^2=-2.
So the simplified version of this fraction given is:
The last simplification come from me multiplying fraction by -1/-1.
The discriminant is : (1)^2 + (-4)*(-3)*(2) = 1+24 = 25
Using the given information and formula, replace d with 14 and π with 3.14
C = 14 * 3.14
C = 43.96 ft.

Answer:
x=31
Step-by-step explanation:
QPC is a triangle. All angles of a triangle adds up to 180.
(x+11)+(2x+6)+70=180
x+11+2x+6+70=180
Combine like terms
3x+87=180
Subtract 87 from both sides
3x+87-87=180-87
3x=93
Divide both sides by 3
x=31
