Wewaii [24]
X to the one half power, over x to the three eighteenth power is equal to x to the one half power, divided by x to the one sixth power, which equals x to the power of (one half minus one sixth), or x to the one third power. 

<span>The twenty seventh root of the quantity of x to the second times x to the third times x to the fourth equals the twenty seventh root of x to the ninth power which equals x to the one third power. </span>

2x^2+2x is it simplified
Tpy6a [65]

Answer:

Yes it is simplified

Step-by-step explanation:

2x^2 is not a like term to 2x because 2x does not have an exponent. Therefore, you cannot add 2x to 2x^2. So it is as simplified as it can be at this point

Shawna and her best friend Keisha go shopping. The function p(t) = 3x4 + 2x3 − 4x2 + 21 represents how much money each girl spen
Komok [63]

Shawna and her best friend Keisha together spend $ 138

<h3><u>Solution:</u></h3>

Given that, Shawna and her best friend Keisha go shopping.

The function given for money each girl spent based on the number of hours they were shopping is:

p(t)=3 x^{4}+2 x^{3}-4 x^{2}+21

<em><u>Find the amount of money that each girl spent</u></em>

For t = 2 hours

\begin{array}{l}{\mathrm{p}(2)=3(2)^{4}+2(2)^{3}-4(2)^{2}+21} \\\\ {\mathrm{p}(2)=3 \times 16+2 \times 8-4 \times 4+21} \\\\ {\mathrm{p}(2)=48+16-16+21} \\\\ {\mathrm{p}(2)=69}\end{array}

<em><u>Find the amount of money that they spend together</u></em>

Multiply by 2 the amount of money that each girl spent

2 \times 69 = 138
