Which equation shows the best estimate for 4,310 ÷ 72 using compatible numbers? 4,900 ÷ 70 = 70
4,200 ÷ 70 = 60
4,000 ÷ 80 = 50
4,000 ÷ 100 = 40

i think your answer is going to be 4,200/70 = 70

^^

step-by-step explanation:

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
