Answer:
her grandson would be 7 and her granddaughter would be 5.
Step-by-step explanation:
their ages together is 12. we divide that by the two grandchildren, and adjust it to where they are to years apart.
12÷2=6
6+6 + adjusted = 5 and 7.
to fact check 5+7=12, and 7 is two numbers above 5.
I think it is D) positive association, non-linear
(-6 - 5i)(1 - 3i)
you foil this like you would any other set of binomials, so you'll multiply negative 6 and 1, then -5i and 1, etc:
-6 - 5i + 9i - 15
5i and 3i simplify to -15 because 5*3 is 15, and i*i = -1
then you just add like terms:
-21 - 5i + 9i
-21 + 4i is your answer.
