i think that is 147
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) the two members of the expression has 4x in common, so we can rewrite it as: 4x(3x-2)
2) we have to find two numbers that multipied give -36 and that added up give 5
the two number are 9 and -4
we can rewrite the expression as : (x+9)(x-4)
3) we have to solve the associated equation
3x^2+10x+8 = 0
Δ/4 = 25-24 = 1
x1 = (-5+1)/3 = -4/3
x2 = (-5-1)/3 = -2
now we can rewrite the expression as
3(x+4/3)(x+2) = (3x+4)(x+2)

sinh(ln(4)) = (exp(ln(4)) - exp(-ln(4)))/2 = (4 - 1/4)/2 = 15/8 = 1.875
sinh(4) = (exp(4) - exp(-4))/2 ≈ 27.28992
