Which equation represents a linear function? (5 points) A) Equation 1: y = 2x2 + 1
B) Equation 2: y2 = 3x + 1
C) Equation 3: y = 5x − 1
D) Equation 4: y = 4x4 − 1

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)

the answer is 6

hope this !
