Reza and nina are racing the length of a pool. after 20 seconds,
reza has swum 1/4 of the length of the pool, and nina has swum 3/4
of the length of the pool.

which best describes who covered more distance in 20 seconds?
reza covered more distance in 20 seconds because 3/4> 1/4 .
reza covered more distance in 20 seconds because 1/4> 3/4 .
nina covered more distance in 20 seconds because 3/4> 1/4 .
nina covered more distance in 20 seconds because 1/4> 3/4 .

i think this could be a possible answer (1 / 84) -1

good luck! : d

it is true

step-by-step explanation:

all the combinations add up i used   calculator

triangle and cube

step-by-step explanation:

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)
