Answer:
N + 3 = -5
n= -8
N-4=9
n=13
4+N=10
n=6
-10+N=3
n=13
N-10=1
n=11
-11+n=-12
n=-1
N+19=20
n=1
15+N=-10
n=-25
N-6=-12
n=-6
N+4=16
n=12
Step-by-step explanation:
The side lengths on the new dilated rectangle will be 30cm and 16cm
<h3>How to calculate dilation</h3>
Given the following parameters
- Length = 8cm
- Breadth = 15cm
If the length and breadth are dilated by a factor of 2, hence the new dimansion will be:
New length = 2(15) =30cm
New width =2(8) = 16cm
Hence the side lengths on the new dilated rectangle will be 30cm and 16cm

Okay so first we need to know how much work each worker can do so we have two divide the 15 hours by 6 workers.
i decided to make to hours into half hours just to make it easier
in the end every worker can do 2 hours and 30 minutes of work
but if you add in 7 more workers it will take about 1.1 hour for each worker to complete the work thus getting it done in 7 hours
5 is to 7 as is to 49 is to 51
