This will not factor so you can use the quadratic formula
x = [- (-3) +/- sqrt(9 - 4*5*-4) / 10
= (3 +/- sqrt 89) / 10
= 3 + 9.434 / 10 or 3 - 9.434 / 10
= 1.24 , -0.64 to the nearest hundredth
Answer: fist one is 4 & second one is 1

Answer:
2
Step-by-step explanation:
2(z)+2 = 4
2z = 2 x 2 = 4
Combine like terms: r+8r=9r. subtract 11 from both sides 9r=18. r=2
The answer is 1.9! Explanation: 20.3-18.4=1.9
