Answer:
k = 4 + 5.10i , 4 - 5.10i
Step-by-step explanation:
8k - k^2 = 42
k^2 - 8k + 42 = 0
Completing the square:-
(k - 4)^2 - 16 +42 = 0
(k - 4)^2 = -26
k- 4 = +/-sqrt26
k = 4 + sqrt26 or 4 - sqrt26
k = 4 + 5.10i , 4 - 5.10i
For this problem, you will have to use PEMDAS (Parentheses) (Exponents) (Multiplication/Division) (Addition/Subtraction)
First of all, you will want to solve for the values inside the parentheses first
40 <span>÷ 1+3-(21)+7-5 Now check for anything that includes multiplication/division and do that
40+3-21+7-5 All you have left now is addition and subtraction. It must go from left to right, therefore if addition is first, do addition, if subtraction is first, then do subtraction.
Final answer = 24</span>
Answer:
-x
Step-by-step explanation:
First you cancel the x^3 and the -x^3 because together, they equal 0.
Then you are left with 3x - 4x.
That equals -x.
