The perimeter of the square below can be described by the expression 64 + 12y. A square.

Which of the expressions describes the length of one side of the square?

A square has 4 equal sides.

64/4 = 16; 12 y/4 = 3 y
16 + 12y
4 + 12y
4 + 3y
16 + 3y

the answer would be 16+3y

Step-by-step explanation:

length of one side of a square is perimeter/4

so (64+12y)/4

64/4 +12y/4

=16+3y

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
