andrew=7×£3=£21
Answer:
y=1/2x+5/2
Step-by-step explanation:
4-3=1
3-1=2
m=1/2x
So now you have y=1/2x
Insert into equation
y=1/2x+?
Now sub you slope in to last points, and you get 5/2
So now you final answer is:
y=1/2x+5/2
Answer:

Step-by-step explanation:
4th term+5th term = 
5th term = 
4th term = 



5th term= 
Common difference = 5th term - 4th term


Answer:
Two ways you can group them is:
(4+7)+2
4+(7+2)
They will both give you the same answer of 13.
(4+7)+2 4+(7+2)
11+2= 13 4+9= 13
<h3>Given:-</h3>
- radius = 7 inches
- height = 9 inches

<h3>To find:</h3>

we know:-


So:-
⇢SA of cylinder=2πrh+2πr²

⇢SA of cylinder = 2πr(h+r)

⇢SA of cylinder = 2 × π × 7(7 + 9)

⇢SA of cylinder = 2 × π × 7 (16)

⇢SA of cylinder = 2 × π × 112

⇢SA of cylinder = 2 × 112 × π

⇢SA of cylinder = 224π inches ²
