(3x² + 2x - 3) (x-1),

The product of the above factors is: 3x³ - x² - 5x + 3

Distributive property of multiplication

x(3x² + 2x - 3) - 1(3x² + 2x - 3)
3x³ + 2x² - 3x - 3x² - 2x + 3

Group like terms:
3x³ + 2x² - 3x² - 3x - 2x + 3

Find the surface area of this rectangular prism: Don't forget to show the unit of measure.

Ann [662]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the attachment of the prism is not given.

From the attachment:

$L =10cm$ -- Length

$W = 4cm$ -- Width

$H=5cm$ -- Height

Required

Determine the volume

So, the volume is:

$Volume = Length * Width (* Height$

$Volume = 10cm * 4cm * 5cm$

$Volume = 200cm^3$

I have k quarters, five less quarters than nickels and one more than twice as many dimes as quarters. Find the value of the coin

Alenkinab [10]

Answer:

(35k + 20) cents

Step-by-step explanation:

First of all, let us have the value of each unit:

1 quarter = 25 cents

1 nickel = 5 cents

1 dime = 10 cents

Given that number of quarter = k

Quarters are 5 lesser than Nickels, so number of nickels = k+5

One more than twice as many dimes as quarters:

k = 2 $\times$ Number of Dimes + 1

So, number of dimes = $\frac{1}{2}(k-1)$

Value of quarters = $25 \times k$ cents

Value of nickels = $5 \times (k+5) = (5k+25)\ cents$

Value of dimes = $\frac{1}{2}(k-1) \times 10 = (5k-5)\ cents$

So, total value of coins =

$25k + 5k +25 +5k-5\\\Rightarrow (35k+20)\ cents$
