In inductive reasoning what is the next number 3,13,22,30,37,43

48

Step-by-step explanation: It goes up by the receding numbers starting from ten so 3+10=13+9=22+8=30+7=37+6=43+5=48.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
