Which expression has a value of 13?

(20 ÷ 4) − 4 + 3 x 2

(18 ÷ 2) + 6 ÷ 6 + 3

(16 ÷ 4) + 3 x 4 − 1

(10 ÷ 2) − 3 + 4 x 2

(18/2)+6/6+3

Step-by-step explanation:

(18/2)=9

6/6=1

9+1=10

10+3=13

Use PEMDAS

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

the answers might not be correct use at own risk

one set of data has more variation than the other. hope this !
