Answer:P=2x + 2y + 8
Step-by-step explanation: Perimeter (p) =2L+ 2w
P= 2(x+5)+2(y-1)
Remove bracket
P=2x+ 10 +2y - 2
P=2x+2y+8
Every prime greater than 2 is oddNo even number greater than 2 is prime
Answer:
If 0.2 = 20%, The probability that 1 person will be infected is 100%, according to theory.
Answer:
The distance is 
or 
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
Solutions
⇒ Given
Salary - $ 20
Spends - $ 14
The first step is to subtract 14 from 20. When we do this, we will know how much he saves.

Calculations
20 - 14 = 6
He saves $ 6 each week.
Now we have to find how many times 6 goes into 300. To do this we have to divide.
300 ÷ 6 = 50
<span>It is going to take him 50 weeks. </span>
