Each liter of water weighs 1 kg, so the weight of the water in a cubic meter is 1,000 kg.
Answer: 2x^2 -16t
25t -20
Step-by-step explanation:
Multiply the corresponding terms to find out which answer belongs in each box. For the top left box you would multiply 5t x 4t = 20t^2. For the top right multiply -4 x 4t = -16t. For bottom left box multiply 5t x 5 = 25t and for the bottom right box multiple -4 x 5 = -20.
Answer: the second one
Step-by-step explanation:
The first one is reflection over the x-axis, rotated, and translated. The third one is rotated 90 degrees
