Choose the correct simplification of (4x − 3)(3x2 − 4x − 3).

tester [92]

$(4x - 3)(3x^2 - 4x - 3)$

$=4x\cdot \:3x^2+4x\left(-4x\right)+4x\left(-3\right)-3\cdot \:3x^2-3\left(-4x\right)-3\left(-3\right)$

$=4x\cdot \:3x^2-4x\cdot \:4x-4x\cdot \:3-3\cdot \:3x^2+3\cdot \:4x+3\cdot \:3$

$\mathrm{Simplify}\:4x\cdot \:3x^2-4x\cdot \:4x-4x\cdot \:3-3\cdot \:3x^2+3\cdot \:4x+3\cdot \:3:\quad 12x^3-25x^2+9$

$=12x^3-25x^2+9$

Martin has a shoe box with the dimensions 4 inches, by 6 inches, by 10 inches. He wants to determine if a relay baton inches wil

kicyunya [14]

Answer:

10 inches.

Step-by-step explanation:

First we need to find what is the bigger dimension of the box, because the relay baton will occupy the box, and the larger dimension of the relay baton (that is, it's length) need to be less or equal than the larger dimension of the box.

The dimensions of the box are: 4 inches, 6 inches and 10 inches.

The larger dimension of the box is 10 inches. So, If we want the relay baton to fit in the box, the maximum length it can have is 10 inches.

You are in a traffic jam that is 7/8 mile long. The cars are in one lane bumper to bumper. The average length of a car is 0.003

KengaRu [80]

Answer:

Step-by-step explanation:

The average length of each car is

0.003 mile. The length of each car includes the bumper. The cars are in one lane. This means all the cars can be assumed to form a long line of cars that is uniform in length. This length is divided into equal lengths if cars.

The length of the traffic jam which is also the length of the line of is 7/8 = 0.875 mile long.

The number of cars would be in the that would be in the traffic jam will be length of the traffic jam/ length of each car. It becomes

0.875/0.003 = 292 cars

Step-by-step explanation:

*Note:

Please excuse my bad handwriting :)

Step 1: Define

Identify

p(x) = x³ - 21x - 20

Linear factor (x - 5)

Step 2: Factor

Option 1: Factoring cubes formula

Factor [Factoring Cubes]: p(x) = (x - 5)(x² + 5x + 4)
Factor: p(x) = (x - 5)(x + 4)(x + 1)
