This is my question for now

V = 540cm3 (E)

Step-by-step explanation:

Area of a square:

A = a2

Perimeter of a Square

P = 4a

Polygon diagonals of a square

q = √(2a2) = a√2

Side of a Square

a = √A

a = P/4

a = q / √2

Square Calculations

Calculate q, P, A | Given a

Given the length of a side calculate the diagonal, area and perimeter

q = a√2

A = a2

P = 4a

Calculate a, P, A | Given q

Given the diagonal length calculate the side length, perimeter, and area

a = q / √2

P = 4a

A = a2

Calculate a, q, A | Given P

Given the perimeter calculate the side length, diagonal, and area

a = P/4

q = a√2

A = a2

Calculate a, q, P | Given A

Given the area calculate the length of the sides, diagonal, and the perimeter

a = √A

q = a√2

P = 4a

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
