For
(c+d)(ex+f)
the expanded form is
dex^2+dex+cfx+df
(ce)x^2+(de+cf)x+(df)
ax^2+bx+c
the value of a is ce
the value of b is de+cf
the value of c is df
so
(-2x+3)(x+8)
(-2x+3)(1x+8)
b is 3*1+-2*8=3-16=-13
answer is -13
so pick 13 because we have -B, so B=13
To find LCM
factor and eliminate ones already represented
1=1
2=2
3=3
4=2*2
5=5
1*2*2*3*5=60
Answer:
402 days.
Step-by-step explanation:
f(x)=1+1.5ln(x+1)
When f() = 10 we have:
10 = 1 + 1.5ln (x + 1)
ln (x + 1) = (10-1) / 1.5 = 6
x + 1 = e^6
x = e^6 - 1 = 402.4.
C.) 0.0001 is a power of ten
