9 x 2 = 18 Therefore: twice
8 is twice as big as 4. 9 x 8 is twice as big as 9 x 4.
No. 8/9 is twice as large.
27
The answer is that 18 pounds is twice as heavy as 9 pounds because 18 divided by 2 equals 9. Therefore, 18 pounds is double the weight of 9 pounds.
If the width is 9' and the length is twice that, the length is 18'; the perimeter is twice the length plus twice the width, which is 36' + 18' = 54 feet.
um, 9.
As an algebraic expression it is: 2x-9
The product of 9 multiplied by 6 is 54.
It is: 2(9+8) = 34
