Answer:
46 inches
Step-by-step explanation:
Since every foot is 12 inches you will do 3 × 12, which equals 36. You aren't done yet though. Since there's an added 10 inches you will add 10 inches to 36. 36 + 10 = 46. Hope this helps!
1cm = 10mm
21cm = 10 x 21 = 210 mm
<span>10(4*10÷(6²-4²)+1)
10(40÷(36+16)+1)
</span>10(40÷(52)+1)
10(40÷(52)+1)
10(0.7692307692+1)
10(1.7692307692)
17.692307692
You should probably round that:
17.69
Step-by-step explanation:
supplentary means they add to 180
