Answer:
(C)2
Step-by-step explanation:
Given the polynomial:
where x is the missing exponent.
We desire our polynomial to be a binomial (have two terms) after simplification.
We observe that the first and second term are positive and negative of almost the same term.
Therefore, we rewrite the polynomial in such a way that the first and second term cancels out.
This is:
Therefore, the missing exponent on the m in the second term is 2.
Answer:
KM = √70 ≈ 8.367
Step-by-step explanation:
FD is a midsegment whose length (8) corresponds to the average of the numbers of ratio units of LM : KN = 3 : 5. That is, each of those ratio units must be 2 length units, so KN = 10.
∠MKN = ∠KML = ∠N because the first two angles are alternate interior angles where transversal MK crosses parallel lines ML and KN. The latter two of these angles are equal because the problem statement says so.
These angle relationships make ΔKMN an isosceles triangle, with E the midpoint of the base. That is, KE = 5. We are told ME = 3√5, so the Pythagorean theorem tells us ...
... KM² = KE² +ME² = 5² +(3√5)² = 70
... KM = √70 . . . . . take the square root
