Answer:

  C.  2(k +2)(k +5)(k +1)

Step-by-step explanation:

The LCM will be the product of unique factors.

  (k^2 + 3k + 2)=(k+1)(k+2)\\(2k^2 + 14k + 20)=2(k+2)(k+5)

The unique factors are 2, (k+1), (k+2), (k+5), so the LCM is their product:

  2(k+1)(k+2)(k+5) . . . . matches choice C

Answer:

  √869 ≈ 29.48 square units

Step-by-step explanation:

The vector cross product is ...

  (3·1 -5·4, -6·1 +2·4, 6·5 -2·3) = (-17, 2, 24)

The area is the magnitude of this vector, so is ...

  √((-17)² +2² +24²) = √(289 +4 +576) = √869 ≈ 29.48

The area is about 29.48 square units.

Well each ladder has 30, and then it depends on how each person climbs their ladder. One climb at the rate of -2 per second. The other climb at the rate of 1 per second. Just x is equal to 1, that's why I didnt put 1x.
Equation: 30 + -2x = 30 + x
