(14-3x)2 simplified using the distributive property.

ivolga24 [154]

Answer: 28-6x

This is the same as -6x+28

===============================

To get that answer, you multiply each term inside the parenthesis by the outer term 2

14 * 2 = 28

-3x * 2 = -6x

So,

(14-3x)*2 = 14*2 - 3x*2 = 28-6x

----------

The distribution rule says

a(b-c) = ab-ac

which is the same as saying

(b-c)a = ba-ca

We can flip things around because we can multiply in any order.

Becky purchased a home entertainment center for $2,254 using an 18-month deferred payment plan with an interest rate of 22.48%.

Anna [14]

Answer:

$76.69

Step-by-step explanation:

Purchase price = $2254

Interest rate on purchase = 22.48% = 0.2248

Payment time-line = 3 years = (3 * 12) = 36 months

To calculate the Monthly payment :

Total amount to be paid = (Purchase price + interest on the purchase price)

Total amount to be paid :

2254 + (0.2248*2254) = 2760.6992

Monthly payment :

Total amount / number of months

2760.6992 / 36

= 76.686088

= $76.69

what is the formula for calculating the length of the space diagonal of a right rectangular prism on the basis of the prism's le

Lady bird [3.3K]

The diagonal of a right rectangular prism is the line that connect opposite vertices. In other word is the distance from corner to corner in the right rectangular prism. Since the diagonal of a right rectangular prism is the hypotenuse of a right triangle, we are going to use a variation of the Pythagorean theorem to find it. In essence, we just need to add another dimension to the Pythagorean theorem; in this case the height of our prism:

We can conclude that the formula to calculate the length of the diagonal of a right rectangular prism is: $d= \sqrt{l^2+w^2+h^2}$
where
$d$ is the length of the diagonal.
$l$ is the length of the rectangular base of the prism.
$w$ is the width of the rectangular base of the prism.
$h$ is the height of the prism.
