The length of a rectangle is represented by x, the width is represented by 6x^2-4x-2. What is the area of the rectangle?
navik [9.2K]

Answer:

2x(3x^2-2x-1)

Step-by-step explanation:

Area of a rectangle is simply length times width

{6x^2-4x-2} * x    would be the area

That can be simplified to

6x^3-4x^2-2x

Which can be further simplified to

2x(3x^2-2x-1)

A basketball player scored 29 points in a game. The number of three-point field goals the player made was 29 less than three tim
jek_recluse [69]
If you let x represent the number of free throws.         
let y represent the number of two-point field goal.         
let z represent the number of three-point shots made.

Then the correct system of linear equations is as follows: 

x + 2y + 3z = 29 (The total number of points scored is 29.)
z = 3x - 29 (The number of 3-pointers was 29 less than 3 times the number of free throws.)
2y = z + 15 (Twice the number of 2-point shots made was 15 more than the number of 3-pointers.) 

Solution:
This basketball player scored 10 points via free throws (10 at 1 point each), 16 points via 8 two-point shots made, and 3 points via 1 three-point shots made. So, in the choice its letter D.

Please help; I’m hopeless.
Yuliya22 [10]
Well, you have to find 2 of the same number that add together to make that middle number before the c. Then you have to multiply those 2 identical numbers together to find the value of c!——————————————————————So! For number 10, 7+7 is 14, so 7 and 7 are your two identical numbers.——————————————————————Then you have to multiply them to get c! 7•7=49, so 49 is c.——————————————————————I’ll do 11 for you as well, 12+12=24, and 12•12=144, so 144 is c.

your brand new 20,000 car will depreciate to 2,000 at a constant rate in ten years. Write a linear model relating the value "v"
koban [17]
Define
v =  value after t years.

Therefore the linear model is
v = mt + c
where
 m = depreciation rate
t = years since purchase
c =  constant

When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000

When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800

Answer:
The linear model is
v = -1800t + 20000
