Answer:
Correct to 1dp
127.3 cm = 127.0 cm
86.5 cm = 87.0 cm
Upper limits:
127.0 cm = 127.05 cm
87.0 cm = 87.05 cm
Lower Limits:
127.0 cm = 126.95 cm
87.0 cm = 86.95 cm
upper limit of perimeter of rectangle:
P = 2(l+w)
= 2(127.05 + 87.05)
= 2(214.1)
= 428.2 cm
lower limit of perimeter of rectangle:
P = 2(l+w)
= 2(126.95 + 86.95)
= 2(213.9)
= 427.8 cm
therefore;
![427.8 cm \leqslant perimeter < 428.2cm](https://tex.z-dn.net/?f=427.8%20cm%20%5Cleqslant%20perimeter%20%3C%20428.2cm)
Answer:
If you substitute (-1,2) meaning x and y
2=3(-1)-2
2=-3-2
2= -1
Step-by-step explanation:
he's incorrect since the solution does not equal 2 on both sides
Step-by-step explanation:
60: 180: 240
