Here mark the angles
- m<FHG=75
- m<FGH=55
- m<GHI=59°
- m<GIH=63°
By using angle sum property
So
- m<FGH < m<IGH <m<GHI <m<GIH <m <FHG
So
Y=|x+7|-9
Im not sure how to explain this sorry
YEAH so greater than or equal to is filled in
<span>the answer would be 79.623 times 4.83</span>
Try to get it into form
(ax+b)(cx+d)
a,b,c,d can be negative or positive
3x^2+7x+2
2 and 7 are positive so b and d will be positive as well
3 is prime so we have to have
(3x+?)(1x+?)
2 is also prime
try
(3x+2)(1x+1), expanded it is 3x^2+5x+2, nope
(3x+1)(x+2), expanded is 3x^2+7x+2, yep
mostly a trial and error sort of thing
after some practice, it might get easier for you to see
