<h3>The answer to your question is k (-3) = 21!</h3>
Here's how I got this answer:
<em><u>K(a) = 2a^2 - a </u></em>
<em><u>K(a) = 2a^2 - a K(-3) = 2(-3)^2 - (-3)</u></em>
<em><u>K(a) = 2a^2 - a K(-3) = 2(-3)^2 - (-3)K(-3) = 2(9) + 3</u></em>
<em><u>K(a) = 2a^2 - a K(-3) = 2(-3)^2 - (-3)K(-3) = 2(9) + 3K (-3) = 18 + 3</u></em>
<em><u>K(a) = 2a^2 - a K(-3) = 2(-3)^2 - (-3)K(-3) = 2(9) + 3K (-3) = 18 + 3K (-3) = 21</u></em>
I hope this helps!
Also sorry for the late answer, I just got the notification that you replied to my comment, I hope I came in time!
kx-4=9
Move -4 to the other side. Sign changes from -4 to +4
kx-4+4=9+4
kx=13
Divide by k for kx and 13
Cross out k and k = 1.
x=13/k
Answer: x=13/k
A rectangular prism as 6 sides, 2 of each dimensions.
So this has 2 sides that are 5 x 5
2 sides that are 10 x 5
and 2 sides that are 10 x 5
Find the area of each, multiply by 2 then add them all together:
5 x 5 = 25
10 x 5 = 50
10 x 5 = 50
(25 + 50 + 50) x 2 = 250 m²
The highest number on dice is 6, so nothing can be higher than 12 when you roll 2 of them...
