Answer:
0.4 to 1
Step-by-step explanation:
2 1/2=2.5
you do 1 divided by 2.5 or 1/2.5 and you get 0.4 then add the unit rate of 1.
The place value of 7 in 0.724 is the tenth place.
Rule needed: i^2 = -1
Standard form a + bi
(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
