You estimate 2,641 * 9 by rounding 2,641 to the nearest hundred which would be 2,600 * 9. You can also round 9 to the nearest ten which would be 10. So you could multiply 2,600 by 9 to get 23,400 or multiply 2,600 by 10 to get 26,000.

Answer:

Step-by-step explanation:

㏒ 3+㏒(x+2)=1

㏒3(x+2)=1

3(x+2)=10^1

3x+6=10

3x=10-6=4

x=4/3

so A

$log_{2}x+log_{2}(x+2)=3\\or~log_{2}[x(x+2)]=3\\x(x+2)=2^3\\x^2+2x-8=0\\x^2+4x-2x-8=0\\x(x+4)-2(x+4)=0\\(x+4)(x-2)=0\\x=2,-4\\x=-4 ~is~an~extraneous~solution.\\B$
