Ummmmmmmmmm 7 i think that is the wright answer
Answer: option d is correct .
Step-by-step explanation:
In order to find the same attendance we set both equation equal
8x+191 = -x^2+26x+126
simplifying equation ,we get
x^2 -18x+65=0
(x-5) (x-13) = 0
x =5 or x =13
therefore on 5th day and 13th day both plays attendance is same
and it is obtained by plugging x = 5 in and x =13 in either of the equation.
for x = 5 ,
y = 8(5) +191 = 40+191 = 231
for x = 13
y = 8(13)+191
= 104+191
= 295
therefore option d is correct
Answer:
92
Step-by-step explanation:
angle a and b add up to 180 degrees
4x-20+2x+8=180
add like terms
6x+12=180
x=28
then substitute to get 92
