8. Joyce earns on a graduated commission scale. This past week Joyce sold $23,000 worth of goods. If Joyce earns 5% on her first $10,000 in sales and 10% on all sales over $10,000, how
much money did Joyce earn this week?

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

answer: our required factorization will be

(3x+4)(x²-5)

step-by-step explanation:

since we have given that

now, we will write it as :

so, we get

5(3x+4)

similarly,

here, we get,

2(3x+4)

together it becomes,

hence, our required factorization will be

(3x+4)(x²-5)

if you are factoring then 4(x+3)

if you are simplifying 4x+12
