Factor the polynomials.
1. x^2+11x+18

(x + 9) (x + 2)

Step-by-step explanation:

x² + 11x + 18

x² + 9x + 2x + 18

x(x + 9) + 2(x + 9)

(x + 9) (x + 2)

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
