Answer: AB=7.74in.;m<A
=57*;m<B=33*
Step-by-step explanation
this symbol means degrees *
Let x= number rows
Then x + 5 = number of seats per row
x(x+5) = 126
X^2 + 5x = 126
x^2 + 5x -126 = 0; now factor or use quadratic:
(x+14)(x-9) = 0; so the answers are either -14, or 9, and since -14 is not possible in this case because you can't have a negative number of rows, the answer is 9 rows.
Check work: number of rows = 9, number of seats per row = 9+ 5= 14, and 9 x 14 = 126
72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m
Round 5.2 down to 5 and Round 6.7 to 7.
5+7=12
Answer:
You would just plug in the x’s for the equations above and that will equal your x
Step-by-step explanation:
for example x=1
the equation is x+5
so y equals 1+5=6
y=6
