Chin made an error in his chart showing the multiplication of the binomial by the trinomial. Which change can be made to correct
the chart? The expression 3x3 should be 3x2. The expression 6x should be 6xy. The expression x2y should be x2y2. The expression 4y should be 4y2.

Answer:
The expression 6x should be 6x²
Step-by-step-explanation:
The chart being referred to showing the multiplication of the binomial by the trinomial is given in the attached picture below.
To find out where Chin made an error in his multiplication, and also determine the right expression, let's take a look at each multiplication done. Thus we have:
3x*x² = 3x³
3x*2x = 6x² (here is where the error was made, in the chart, Chin wrote 6x)
3x*4 = 12x
2*x²=2x²
2*2x = 4x
2*4 = 8
Therefore, the expression 6x should be 6x²

Answer: 3.5
Step-by-step explanation:
Given: Dimensions of larger prism = length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm.
Dimensions of smaller prism = length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.
Scale factor =
Since, smaller figure is the original figure and the bigger one is the image.
So, scale factor = [Taking lengths
Hence, the factor to produce the corresponding dimensions of the larger prism = 3.5
