Answer:
a) 13, 10, 16
Step-by-step explanation:
The usual form of the triangle inequality requires the sum of the two shortest sides exceed the longest side (a+b>c). The only choice for which this is true is ...
10 + 13 > 16 . . . . choice A
_____
<em>Comment on the triangle inequality</em>
Some authors also allow the sum to equal the longest side (a+b≥c). In that case, choice B (1+2=3) is also an answer. This "triangle" would look like a line segment of length 3. It has zero area.
Answer:
x = -7/4
Step-by-step explanation:
"Eight times a number equals 4 times that number less 7."
Subtracting 4x from both sides of this equation, we get:
4x = -7
Dividing both sides of this result by 4 yields
x = -7/4
45=k√5
times both sides by √5
45√5=5k
divide both sides by 5
9√5=k

Answer:
∑ (n = 1 to 5) (2·(-4)^(n - 1))
S5 = 2·((-4)^5 - 1)/((-4) - 1) = 410
