Cell phones were sold ata store starting at 8:00 a. m. The number of cell phones sold is modeled by f(x) = 4x2–8x+ 50, where xis the number of hours after 8:00 a. m.The average cost for each phone is modeled by g(x) = 20x2+ 10x+ 200.Create a polynomial R(x) that can beused to model the total revenue.

easy math just plug in a and b

step-by-step explanation:

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question

gimme brainliest > : 3

answer: your answer is c

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
