Set up a problem: .05h+.095(h+1000)=965. .05h+.095h+95=965. Combine like terms: .145h=870. Get the unknown by itself: H=6000. The first hotel was $6,000 the second was 6000+1000=$7,000 :)
(4 + i)(1 - 5i)
First, expand to get rid of parentheses.
Second, gather the like terms which contain the same variables.
Third, add 4 + 5.
Fourth, subtract -20i + i.
Answer:
9 - 19i
What kind of sh*t are you learning man?
Check the picture below.
a)
notice, since lines KP and NL are parallel, they make up the same angle in purple when they hit line MK, and both triangles share the green angle at M.
b)
notice, LP = LK = 14, and in an isosceles twin sides stemming from a vertex make twin angles.
