Answer:
38 stamps of each
Step-by-step explanation:
0 .48 + 0.05 = 0.53
20.14 / 0.53 = 38
verification
0.48 x 38 = 18.24
0.05 x 38 = 1.9
18.24 + 1.9 = 20.14
Answer:
a and b have the same index notation , hence its the same number so answer is 2x3x5 = 30
Answer:
<h2>(6 + i)(2 + 9i) = 3 + 56i</h2>
Step-by-step explanation:
Use FOIL: (a + b)(c + d) = ac + ad + bc + bd
and i² = -1
(6 + i)(2 + 9i) = (6)(2) + (6)(9i) + (i)(2) + (i)(9i)
= 12 + 54i + 2i + 9i²
= 12 + 54i + 2i + 9(-1)
= 12 + 54i + 2i - 9 <em>combine like terms</em>
= (12 - 9) + (54i + 2i)
= 3 + 56i
The answer is b hopefully I helped
