Answer:
so... one cot is $91 and they need 4 for one cabin. so that's 4 times $91 and that's $364.
they have 14 cabins and cots for one cabin are $364. so cots for 14 cabins are 14 times $364. Therefore new cots will cost $5096.
Answer:
2i²+5ij+3ik-12j²-10jk-2k²
Step-by-step explanation:
a=2i-3j-k
b=i+4j+2k
ab = (2i-3j-k) (i+4j+2k)
Multiply both bracket by expanding the bracket
2i(i+4j+2k)-3j(i+4j+2k)-k(i+4j+2k)
Multiply
2i²+8ij+4ik-3ij-12j²-6jk-ik-4jk-2k²
Collect like terms
2i²+8ij-3ij+4ik-ik-12j²-6jk-4jk-2k²
2i²+5ij+3ik-12j²-10jk-2k²
