1 answer:
Answer:
-5 -√8 or ≈ -7.83
Step-by-step explanation:
<u>Solving the quadratic equation, to find its roots:</u>
x^2 + 10x + 25 = 8 ⇒ The left side is perfect square (x+5)^2=8 ⇒ Getting square root of both sides x+5 = ± √8 ⇒ There are 2 roots x = - 5 ± √8 <u>The smallest root is:</u>

Answer:
k=4
Step-by-step explanation:
5-7k=-4(k+1)-3
Distribute
5-7k=-4k-4-3
Combine like terms
5-7k=-4k-7
Add 7k to each side
5-7k +7k = -4k+7k-7
5 = 3k-7
Add 7 to each side
5+7 = 3k-7+7
12 = 3k
Divide by 3
12/3 = 3k/3
4=k
