Answer:
30cm, 60cm
Step-by-step explanation:
Given data
Dimensions of the first rectangle
Length =10cm
Width =20cm
We are told that the dimensions of the second rectangle is gotten by multiplying the first rectangle by 3
Hence the dimensions of the second rectangle is
Length =10*3= 30cm
Width = 20*3= 60cm
Two is equivalent to twenty and 84
-a^2 - 3b^3 + c^2 + 2b^3 - c^2 = -a^2 - b^3 = -(3)^2 - (2)^3 = -(9) - 8 = -9 - 8 = -17
