Find the difference:
VLD [36.1K]

Answer: The difference cannot be found because the indices of the radicals are not the same.

Step-by-step explanation:

To find the difference you need to subtract the radicals. But it is important ot remember the following: To make the subtraction of radicals, the indices and the radicand must be the same.

In this case you have these radicals:

\sqrt[ {8ab}^{3} ]{{ac}^{2} }- \sqrt[ {14ab}^{3}]{{ac}^{2} }

You can observe that the radicands are the same, but their indices are not the same.

Therefore, since the indices are different you cannot subtract these radicals.

Find the distance between the points (-5, 0) and (-4, 1).
choli [55]
The formula of a distance between two points A and B is : 

AB=\sqrt{(x_{B}- x_{A})^2 +( y_{B}- y_{A})^2     }

You should this formula by heart.

Then, you just have to apply it ! :D

Here :

x_{A}=-5
y_{A} =0

x_{B} =-4
y_{B}= 1

Therefore :

\sqrt{(-4-(-5))^2+(1-0)^2}
=  \sqrt{1^2+1^2}
= \sqrt{1+1}
= \sqrt{2}

In short, the answer would be the first option : \sqrt{2}.

Hope this helps !

Bruno uses a piece of wrapping paper with dimensions 1 and one-fourth feet by 3 feet to wrap a gift. What is the total area of t
8_murik_8 [283]

The area of the paper used to wrap the gift is 3 3/4 square feet

<h3>How to determine the total area?</h3>

The dimension is given as:

1 1/4 by 3

The area is the product of the dimensions.

So, we have

Area = 1 1/4 * 3

Express as an improper fraction

Area = 5/4 * 3

Evaluate

Area = 15/4

Rewrite as:

Area = 3 3/4

Hence, the area of the paper used to wrap the gift is 3 3/4 square feet
