Answer:
1900 miles long
Step-by-step explanation:
Because the side has to be increased by 50%
you find half of 8, which is 4 and you add 8+4 because you add the increased amount
8+4=12
you then just find the area.... so 12x12= 144
Answer:
Just a heads up, please google , desmos.com . ive been reccomending this to alot of people. it graphs everything for you while providing adequate reasoning and explanation.
So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2
8 would be the coefficient :)
