Answer:
z = -10
Step-by-step explanation:
5/10 = 1/2
1/2 of 10 = 5
Add the common difference to a term to get the next term.
-10
-10 + (-2) = -12
-12 + (-2) = -14
etc.
The sequence is
-10, -12, -14, -16, -18, -20, -22, -24, -26, -28
X would equal 11. hope this helps. good luck!
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>
