On the number line if you are at positive 8 and add -8 you will lose 8 and get zero! Hope this helps!
Perimeter = namely the length of outside bordering,
well, this is a PENTAgon, or PENTA=5 or namely 5 sides, is regular so each side is the same length, so we have a polygon with 5 sides each measuring 40cm, well, its perimeter is just 40+40+40+40+40 = 200.
Answer:
B. (1,2)
Step-by-step explanation:
Look at the image down below!! (ノ◕ヮ◕)ノ*:・゚✧
perimeter =QR+RS+ST+TU+UQ =26.1
RQ = 5.39
RS = 4.47
ST = 3.61
TU = 4.12
UQ = 8.54
