Answer:
see explanation
Step-by-step explanation:
Given
A = bh
a. substitute b = 6 and h = 5 into the formula
A = × 6 × 5 = × 30 = 15 units²
b.
Multiply both sides of the formula by 2
2A = bh, that is
bh = 2A ← divide both sides by b
h = = = = 8
c
Using
bh = 2A ← divide both sides by h
b = = = = 6
(3 + 2i)(5 + i)
15 + 3i + 10i + 2i^2
15 + 13i - 2
13 + 13i
The answer I believe may be on DN’s website, not entirely sure tho.
5n + 4 = 39
5n = 39 -4
5n = 35
n = 35:5
n = 7
so for example .567 round to the nearest hundred so you would take 6 and if the number is over 5 the everything goes up a number so the answer would be .57
