According to the properties of operations, which equations are correct? Check all that apply. (A) 3a + 3b = 3(a + b)

(B) 6(g – 2h) = 6g – 2h

(C) –3c + 6d = 3(2d – c)

(D) –(4m + 8n) = –2(2m + 4n)

(E) 6u + 9v – 24w = 3(2u + 3v – 8w)

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

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.
