I Think the answer your looking for here is
-2.3 6
------ = . ( -----
-2+3 1
-6
Earnings=20% of sales+7.5h+40
coeficinets are 7.5 and 0.2
vraiables are h and s
constant is 40
B. if h=25 and s=30 input,
7.5*25+0.2*300+40=$287.50
C
new equation is 9h+0.2s+40
coefienct woud be 9 and 0.2
variable is h and s
constant is 4
Answer:
1: 3\sqrt2 - \sqrt14
2: \sqrt21 - 2\sqrt(7)
3: 4\sqrt3 - \sqrt15
4: 2\sqrt5 - \sqrt10
5: -3 + 3\sqrt5
I already gave you these answers man
