Answer:
k= -8
Explaining:
Move variable to the left-hand side and change its sign.
2.25k - 6.5k - 20= 6.5k - 6.5k + 14
Since two opposites add up to zero, remove them from the expression.
2.25k - 6.5k - 20= 14
Collect like terms!
-4.25k = 14 + 20
Add the numbers
-4.25k = 35
Divide both sides of the equation by -4.25
So you will get the answer: k= -8
Answer:
x = 3.2
Step-by-step explanation:
5x + 8 = 24
5x = 16
5+5+5+1
1 is a 1/5 or .2 of a 5
x = 3.2
So, therefore, x would be 3.2
Answer:
A) x = ±2i√3
Step-by-step explanation:
We presume you want to find x such that f(x) = 0.
Divide by 13:
x² + 12 = 0
Subtract 12:
x² = -12
Take the square root:
x = ±i√12 = ±2i√3
