Which binomials are factors of x2−8x−48? Select the two correct answers. x + 4
x−6
x−4
x + 6
x−12
x−8
x + 12
x + 8

(x - 12)(x + 4)

Step-by-step explanation:

The two numbers have equal the b term which is -8

You know you have to subtract to get your answer because there is a minus sign in front of the c term

Find what factors of 48 subtract to = -8

-12 + 4 = -8

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
