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
1+8=3r
9=3r
Both divided by 3
3=r
The length would be w+4 since it is 4 inches more than the width, which is w.
I can help! Do you have an example problem that I can show you step by step?
Answer:
$570
Step-by-step explanation:
