3j + j = 4j
2 + 5j
Add the vectors by components. That is, add the "i" components, and separately add the "j" components.
It is (3j)^6.
c + j = 42; c + 5 = 3(j + 5) c = 42 - j so 42 - j + 5 = 3j + 15 ie 47 - j = 3j + 15 ie 4j = 32 so Jared is 8 and Chim 34 and in 5 years Jared will be 13 and Chim 39. QED
15j2(j + 2)
4
Without information about j, the only possible answer is 3j + 15
3j-13=11+2j 3j-13-2j = 11+2j-2 j-13 = 11 j-13 +13 = 11 + 13 = 24 so j = 24
-3j = 44.7 -j = 44.7 ÷ 3 -j = 14.9 j = -14.9

2 + 5j
3i+2j)*(2i-3j)=0 bcz dot product is zero.
