Answer:
a = 13
b = 0
Step-by-step explanation:
Conjugate of -3 + 2i is -3 - 2i
(-3 + 2i) (-3 - 2i)
We need to expand:
9 + 6i + -6i + -4i^2
-4i^2 =(-4)(-1) = 4
9 + 4 = 13
a = 13
b = 0
Answer:
1156
Step-by-step explanation:
First you get the answer you divide by 9 since it is the denominator and ultimately means how many "pieces" or parts the whole number or amount will be in. You divide by 9 and get 289. Now you have the 1/9 part of 2601. You now multiply this number by 4 to get the 4/9 of 2601. Whennyou multiply by four you get 1156. I hope this makes sense and that it helps you. Please mark brainliest if it did help. :)
