Phone Charges The monthly cost C, in dollars, for calls from the United States to Japan on a certain phone plan is
modeled by the function C(x) = 0.24x + 5, where x is the
number of minutes used.
(a) What is the cost if you talk on the phone for x = 50
minutes?

Hope this ; )

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
