Please i need the answer quick you’ll get 20 points for the answer

$4

Step-by-step explanation:

for plan A you can see per minutes it increases 5 cents so for 20 minutes it would be $36

for plan B you install 20 into your equation

c=30+0.10(20)

.10×20=2

2+30=32

therefore you subtract because its asking for the difference

36-32=4

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
