Solve for k4k=10+2k
1 answer:
K=5
Explanation: you have to rearrange the terms to make the problem look easier to solve then you have you subtract 2 from both sides of the equation then once you get that you have to simplify your answer (combine like terms) then after you divide both sides by 2 and then you should get your answer which is 5 here is a picture of the steps if you don't get it Hope this helps!

Answer:
The base is 4cm and the height is 5cm.
Step-by-step explanation:
This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:
and
Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:
In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:
