Answer:
-10,2
Solve by factoring set each equation equal to 0.
2x-4=0
X+10=0
Simplify
As the risk of an investment decreases, so does the potential for its return
15=-2(2t-1) -- expand brackets
15=-4t+2 -- subtract 2
13=-4t -- switch signs, best to have a positive variable
4t=-13
t=-13/4
On side is 20 Bc L= 30 (L x 2)
=> 60
=> 100 - 60
=> 40 = W
=> W / 2
=>20
1 Side is 20
Hope I Helped
