Answer:
(D)
Step-by-step explanation:
Given: 
To find: Simplify the given expression
Solution: Simplyfying, we get,

![=x^{1} *x^{\frac{2}{7} } \\=x*x^{\frac{2}{7} } \\=x=\sqrt[7]{x^{2} }](https://tex.z-dn.net/?f=%3Dx%5E%7B1%7D%20%2Ax%5E%7B%5Cfrac%7B2%7D%7B7%7D%20%7D%20%5C%5C%3Dx%2Ax%5E%7B%5Cfrac%7B2%7D%7B7%7D%20%7D%20%5C%5C%3Dx%3D%5Csqrt%5B7%5D%7Bx%5E%7B2%7D%20%7D)
Therefore,
can be written as ![x\sqrt[7]{x^{2} }](https://tex.z-dn.net/?f=x%5Csqrt%5B7%5D%7Bx%5E%7B2%7D%20%7D)
The surface area of the pyramid is 18,541 mm² . Option C
<h3>How to determine the surface area</h3>
The formula for surface area of a regular hexagonal prism is expressed as;

Where;
- a is the edge length = 44 millimeters
- h is the height = 95 millimeters
A = 2. 598 ( 44)² + 3(44) 
Simplify
A = 5029. 728 + 132 
Find the square root
A = 5029. 728 + 132(102. 357)
expand the bracket
A = 5029. 728 + 13511. 124
A = 18, 540. 85
A = 18,541 mm² in thee nearest square millimeter
Thus, the surface area of the pyramid is 18,541 mm² . Option C

Answer:
12cm²
Step-by-step explanation:
There were 2 solutions that i came up with. Here is the first one. I rearranged the eqaution by subtracting what is to the right of thr equal sign. Multiply the coefficeint of the first term by the constant 5 x (-1)= -5. Then you would find 2 factors of -5 whose sum equals the coefficient of the middle term which is 20. -5+1= -4 and -1+5=4. the eqaution then comes to 5t^2-20t-1=0. you would solve 5t^2-20t-1=0. you would divide both sides of the equal sign by 5. t^-4t-1/5=0. then t^2-4t=1/5. add 4 to both sides of the equation. so we get 21/5+ 4 + 4t -t^2=21/5. it then comes out to be t^2-4t+t=t-2^2. according to the law of transitivity it is t-2^2=21/5.
t =(20+√420)/10=2+1/5√<span> 105 </span><span>= 4.049 </span>.
The correct answer to A is true
everything else looks okay to me..
I don't know if you are right for the rest since I multiplied and didn't get any of them XD so I'm going to trust you on that. Maybe you should double- check just to be sure though.
