Answer: c=5.4
The two roots are 3/5 and 9/5
Step-by-step explanation:
assume 5x2−12x c=0 is supposed to be 5x^2 - 12x + c = 0
p = (12 + sqrt(144-20c))/10
q = (12 - sqrt(144-20c))/10
p-3q=0,
1.2 + 0.1sqrt(144-20c) +
-3.6 + 0.3sqrt(144-20c) = 0
-2.4 + 0.4sqrt(144-20c) +2.4 = 2.4
sqrt(144-20c) = 2.4/0.4 = 6
144-20c=36
144-36=20c
c = 108/20 = 5.4
5x^2-12x+5.4=0
x = 3/5 or x = 9/5
5(d + 7)
multiply 5 to d, then to 7
5d + 35
Answer:
A = 30
Step-by-step explanation:
The area of a triangle is 
Plug in the values given:
A = 1/2 (10) (6) = 1/2 (60) = 30

Answer:
-1
Step-by-step explanation:
5^(3b-1) = 5^(b-3)
3b-1=b-3 / +1 -b
2b = -2
b = -1
