Doing f(x)-g(x), we have 3^x+10x-(4x-2)=3^x+10x-4x+2=3^x+6x+2=D

Conner and Jana are multiplying (3⁵6⁸)(3⁹6¹⁰).

ad-work [718]

<h3>Conner work is correct. Jana work is wrong</h3>

Solution:

Given that,

Conner and Jana are multiplying:

$(3^56^8)(3^96^{10})$

Given Conner's work is:

$(3^56^8)(3^96^{10}) = 3^{5+9}6^{8+10} = 3^{14}6^{18}$

We have to check if this work is correct

Yes, Conner work is correct

From given,

$(3^56^8)(3^96^{10})\\\\3^5 \times 6^8 \times 3^9 \times 6^{10}$

Use the following law of exponent

$a^m \times a^n = a^{m+n}$

Therefore,

$3^5 \times 6^8 \times 3^9 \times 6^{10} = 3^5 \times 3^9 \times 6^8 \times 6^{10} = 3^{5+9} \times 6^{8+10} = 3^{14} \times 6^{18}$

Given Jana's work is:

$(3^56^8)(3^96^{10}) = 3^{5.9}6^{8.10} = 3^{45}6^{80}$

This is incorrect

The powers of same base has to be added. But here, powers are multiplied which is wrong

I have data on lower class, middle class and upper class. What is a mathematical process that would provide a simple numerical s

Anna007 [38]

Answer:

You can find the mean, by adding all the terms in each data set and dividing by the number of terms. For example, if there were four data points, you would add them all up and divide by four.

hope this helps!

If five squares, each with sides equal to 4n, are divided into 4 equal squares as shown, what will be of the sum of the perimete

vivado [14]

Side of a square = 4n

Side of the smaller square = 4n÷2 = 2n

Perimeter of one smaller square = 2n x 4 = 8n

Perimeter of 20 smaller squares = 8n x 20 = 160n

------------------------------------------------------------------------------
Answer: Perimeter of all the 20 smaller squares = 160n
