The first one. 1 machine= x 5 mach.=5x. Total time is thus 5x+2/3=1 3/4h. Simply find x by doing 105min-40min/5 and that is 13.
Using it's concept, the equivalent expression for the perimeter of the figure is:
2 + 3x2 + 4x2 + 5x2 + 8
<h3>What is the perimeter of a figure?</h3>
The perimeter of a figure is given by the total length of it's boundary.
Hence, for the figure given in this problem, the perimeter is:
2 + 3 + 3 + 4 + 4 + 5 + 8 + 5
2 + 3x2 + 4x2 + 5x2 + 8

three goes into nine three times
which gives you zero then bring the four down
three goes into four one time then subtract four from three then that gives you one than bring the two down which makes twelve and three goes into twelve four times and 12 subtracted from twelve gives zero and then bring the three down and three goes into three 1 time so that equal zero
so in total the whole answer should be 3141
