a family needs to build fencing around their rectangular
home and square swimming pool, depicted below.
the total amount of fencing they need can be written
as i fx + 10.
pool (2x) yd
if x = 5
the family needs
their home
yards of fencing for
yards of fencing for their
home
(2 + 5x) yd
the family needs
pool
(3 + 10x) yd

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

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)
