Step-by-step explanation:
x^3+x^2+4x+4=0
x³+x²+4x=-4
x(x²+x+4)=-4
either
x=-4
or
x²+x+4=-4
x²+x+4+4=0
x²+x+8=0
comparing with ax² +bx+c
a=1
b=1
c=8
x={-1±√{1²-4×1×8}}/2×1
x={-1±√{-31}}/2
<span>In a survey in 2016, it was found that for 10 broad degree categories ranging from engineering to communications, projected average salary of a bachelor’s degree is </span><span>$50,556 in 2016. </span> In 2017, actual was $50,000 ($49,785, to be exact). If t$50,000 will be the basis, and the male who gets a job paying $ 40,760/yr, the difference in his yearly median income from obtaining a bachelor's degree is $9,240.
<span>His pay is 18% lower compared to the median income degree level you obtained, on a monthly basis or yearly basis</span>
8X + 8 > 7x + 14
subtract 7x and 8 from both sides
x > 6
