Answer:
a₅ = 37
Step-by-step explanation:
The term to term rule ' subtract 3 ' is the common difference d of an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₁₂ = 16, then
a₁ + 11d = 16 ← substitute d = - 3
a₁ + 11(- 3) = 16
a₁ - 33 = 16 ( add 33 to both sides )
a₁ = 49 , then
a₅ = 49 + (4 × - 3) = 49 - 12 = 37
Answer:
x² - 6x + 9 = 0
Step-by-step explanation:
Given
(x - 3)² = 0 ( expand left side using FOIL )
x² - 3x - 3x + 9 = 0 ( collect like terms )
x² - 6x + 9 = 0 ← in general form

Option B:
Surface area of the solid is 730 square millimeters.
Solution:
Area of the rectangle = length × breadth
Length of the top net = (25 + 8 + 8) mm = 41 mm
Breadth of the top net = 5 mm
Area of the Top net = 41 mm × 5 mm
= 205 square mm
Area of the second net = 25 mm × 8 mm
= 200 square mm
Area of the third net = 25 mm × 5 mm
= 125 square mm
Area of the bottom net = 25 mm × 8 mm
= 200 square mm
Surface area of the solid = 205 mm + 200 mm + 125 mm + 200 mm
= 730 square mm
Hence surface area of the solid is 730 square millimeters.
Option A is the correct answer.
