Answer:

Area is (x² - 9) units squared.

Step-by-step explanation:

• from difference of squares quadratic property:

{ \boxed{ \rm{(a - b)(a + b) = ( {a}^{2} -  {b}^{2})  }}}

→ a is x

→ b is 3

• Therefore:

{ \tt{area =  {x}^{2} -  {3}^{2}  }} \\  \\ { \tt{area =  {x}^{2} - 9 }}

What will be the answer of this and please give full details
Degger [83]
First off, you have to convert 8 minutes into seconds.
A minute is <em>60 seconds</em>, so multiply 60 by 8.
60×8=480
Now, change 10⁹ into a standard number. Since the number is 10 that is to have an exponent, the exponent, in this case 9, indicates how many zeros are in the standard number.
10⁹=1,000,000,000
So, multiply 480 by 1,000,000,000.
480×1,000,000,000=480,000,000,000
So, the answer is 480,000,000,000.
