Answer:
equals 56y+3x
Step-by-step explanation:
1.584 and I believe that you can round that yourself
.21 is decimal form, 21/100 is the fraction in simplest form.
Ln 54.598... = 4 because ln = log e
answer
D 2
factor
factor the equation
into (x + a) and (x + b) so that a + b = -2 and a * b = -8
the two numbers that meet these conditions are a = -4 and b = 2

find solutions
set both (x - 4) and (x + 2) equal to zero to find your solutions
x - 4 = 0
x = 4
x + 2 = 0
x = -2
add solutions
since the two solutions are x = 4 and x = -2, add them together to get your final answer
4 + (-2) = 2
