I need help PLEASE A group of students is arranging squares into layers to create a project. The first layer has 4 squares. The second layer has 8 squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer?

a. f(1) = 4; f(n) = 4 ⋅ d(n − 1), n > 0
b. f(1) = 4; f(n) = 4 ⋅ d(n + 1), n > 0
c. f(1) = 4; f(n) = 4 + d(n + 1), n > 0
d. f(1) = 4; f(n) = 4 + d(n − 1), n > 0

Find the height of a square pyramid that has the volume of 32 ft.³ and a base lengthof 4 feet

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Complete the solution of the equation. find the value of y when x equals to 1 9x-5y=29
