Answer:
2(3·34)
Step-by-step explanation:
Find the GCF (Greatest Common Factor) of 6 and 68. It is 2. So we can put 2 out of the parenthesis and factor 6 and 68:
2(3·34)
You can't simplify this equation anymore.

Eexplanation:
16. Suppose the roots are α and kα. Then we can write the equation as ...
a(x -α)(x -kα) = 0
ax² -ax(α +kα) +akα² = 0
Comparing to the original equation, we can equate coefficients to get ...
Solving the first for α gives ...
α = -b/(a(1+k)
Substituting into the second, we have ...
c = ak(-b/(a(1+k)))²
Multiplying by a(1+k)², we get ...
(1+k)²ac = kb²
Using k=2 gives ...
9ac = 2b² . . . . . as required
__
17. Using the previous result with k=1 (equal roots), we have ...
(1+k)²ac = kb²
4ac = b² . . . . . for k=1

<em>Additional comment</em>
We observed that the problems were similar, but had different factors relating the roots. So, we elected to solve the general case, then fill in the specific values for the two problems.

Answer:
12 inches
Step-by-step explanation:
30-13=17
17-5= 12
Use information about the triangle's perimeter, to find the side length of C.
If the triangle frame is a right triangle, than you could use the Pythagorean Theorem and use the following formula, a^2 + b^2 = c^2, to find the measure of side c.
Have a great rest of your day, and I hope this helps!
