9. Earth turns on its axis once every 24 h. How many hours does earth take to complete 2 1/4 turns

54

Step-by-step explanation:

24* 2.25= 54

(.25 is 1/4 in decimal form)

2x=70  

x=70/2

x=35

thats the answer

step-by-step explanation:

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)
