The side lengths of the square (4ft) are enlarged by a scale factor of 3. What will be the area of the new square?

144 ft

Step-by-step explanation:

start with the sides and multiply by 3. that is 12. and to find the area of a square is to multiply 2 of it's sides meaning 12×12=144

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
