-23 - 10x < 47 is x > -7 (BUT WITH A LINE UNDER IT!!)

Explanation:
You have to add 23 to both sides making it 70. Then, when you divide or multiply with these inequalities you flip the sign. So when you divide a negative and a positive number, the answer is always negative. So 70 divided by -10 is -7

Ulises lives 1.5 mi from school. Convert the distance to feet.

Sveta_85 [38]

Step-by-step explanation:

Since 1 mi. equals 5,280 feet, you divide 5,280 by 2 to get half of a mile.

5,280 / 2 = 2,640 is half of a mile

Then add to get the answer:

5,280 + 2,640 = 7,920

Therefore, your answer is 7,920, 7,920 is 1.5 miles.

Multiply the following polynomial and write the resulting polynomial in descending order. (3x-8)(2x^2+4x-9)

Step2247 [10]

$(3x-8)(2x^2+4x-9)=6x^3+12x^2-27x-16x^2-32x+72=6x^3-4x^2-59x+72$

Value of the coefficient of the $x^3$ term is $\boxed{6}$

Value of the coefficient of the $x^2$ term is $\boxed{-4}$

Value of the coefficient of the x term is $\boxed{-59}$

The value of the constant is $\boxed{72}$
