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 $\boxed{72}$

Ierofanga [76]

Given ,

Concentrate= 250 mL

Water = 1 liter = 1000 mL

A) ratio is 250:1000 = 1:4

B) for 250 mL it is 1 liter now for 2000mL it is X .

=> x = 2000/250 = 8 liters

C) volume of water in 6L of made up juice is 1500 mL

D) 1 liter - 5 glasses

For 80 glasses it would be 80/5 = 16 glasses

Answer: x=5

Step-by-step explanation:

Substitute 17 for n(x)

17=2x+7

Subtract 7 from both sides

10=2x

Divide each side by 2 to get the x by itself

x=5
