Answer:

$360

Step-by-step explanation:

This is because the discount is $90 since 0.20 (20%) x 450 is 90.

To find the sales price, you have to subtract the discount by the original price.

450 - 90 = 360, therefore the sales price is $360.

What is the factored term form of 2x^3+4x^2-x
Westkost [7]

Answer: x(2x^2+4x-1)

Step-by-step explanation:

2x³+4x²-x, first find the Greatest Common Factor (GCF), which is x. To find the GCF, look at what all the numbers have in common, and then see if it has the greatest value. Next factor out the GCF.

x(\frac{2x^3}{x} + \frac{4x^2}{x}-\frac{x}{x}  ) Simplify each term in the parentheses.

x(2x^2+4x-1)

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

12. A carpenter made two tables. The first table is 4 feet
Arte-miy333 [17]

Answer:

a. True

b. True

c. False

d. False

Step-by-step explanation:

<u>First Table</u>

Length=10 feet, Width=4 feet

Area =10 X 4=40 Square Feet

<u>Second Table</u>

The second table is half as long  as the first table.

Length =0.5 X 10 =5 feet

Area=5 X Width= 5w

The area of the second table is one  fourth the area of the first table.

Area of Second Table =\frac{1}{4} X Area of first table

5w=\frac{1}{4} X 40

5w=10

Width of the Second table, w=2 feet

The following are true.

(a)The width of the second  table is 2 feet.

(b) The area of the second  table is 10 square feet.
