Notice the picture below, see the length "l"?
well

solve for "w", to find the width,
what's the length? well, l = 11/4 w
Answer: (y-c)/m
Reasoning:
Subtract c from both sides [ y-c=mx+c-c ]
Divide m from both sides [ (y-c)/m=mx/m ]
Perimeter of rectangle =2 X( L + w)
width=3
perimeter=22
length =?
2(L+3) =22
=>2L+6 =22
=>2L = 22-6
=>2L =16
=>L = 16/2
=>L=8 ..
Hope it helps !!!
Answer: 45
Step-by-step explanation:
As we can see here, the relation is as follows:
(1)(4)+1 = 4+1= 5
(2)(5)+2 = 10+2 =12
(3)(6)+3 = 18+3= 21
Then, if we follow the same pattern:
(4)(7)+4 = 28+4= 32
Hence:
(5)(8)+5 = 40+5=45
