However, I will try to help you out with some information.
A cylinder is a three-dimensional geometric solid.
It has the same shape as a soda can.
<u>As for the bases, they have the following properties:</u>
1- the bases have a circular (disc) shape

3- the bases are parallel to each other
Hope this helps :)
<h3>
Correct Question :</h3>
Express in arithmetic :
Seven added to double a number.
<h3>
Solution :</h3>
Let the unknown be x.
Then, double of the number = 2x.
Atq,
2x+7
Hence,seven added to double a number = 2x+7
Answer:
The expression equal to 2x^(2)+8 is:
First option (2x-4i)(x+2i)
Step-by-step explanation:
If we multiply
(2x-4i)(x+2i)=(2x)(x)+(2x)(2i)-(4i)(x)-4i(2i)
(2x-4i)(x+2i)=2x^(1+1)+4xi-4xi-8i^(1+1)
Simplifying:
(2x-4i)(x+2i)=2x^2-8i^2
and i^2=-1, then:
(2x-4i)(x+2i)=2x^2-8(-1)
Multiplying:
(2x-4i)(x+2i)=2x^2+8
