Answer:
122.
Step-by-step explanation:
nthe term = a1 + d(n - 1) so here:
20th term = -30 + 8(20 - 1)
- 30 + 152
= 122.
Part 1:
perimeter of a rectangle = 2(L + W)
W = 5/6 L
perimeter of a rectangle = 2( L + 5/6L)
Part 2:
perimeter of the rectangle is 44 inches
perimeter of a rectangle = 2(L+5/6L)
44 = 2(L+5/6L)
44 = 2L + 10/6 L
44 = 3 2/3 L
L = 12
W = 5/6 L
W = 5/6 x 12
W = 10
Area = L x W
Area = 12 x 10
Area = 120 square inches
Answer:
54 + 39i
Step-by-step explanation:
Given
3i(2 - 5i)(4 + i) ← expand factors using FOIL
= 3i(8 - 18i - 5i² ) → using i² = - 1
= 3i(13 - 18i) ← distribute parenthesis by 3i
= 39i - 54i²
= 54 + 39i
