Select all expressions that are equivalent to each other. A. 3^(2+2)
B. 3 ^(2+2x)
C. 9(3)^2x
D. (3^2 x 3)^x
E. (3x3+)^2

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

the answer to this in exact form is 4/35 but in decimal form its 0.1142857
