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
Answer:
3x=10+13x
We simplify the equation to the form, which is simple to understand
3x=10+13x
We move all terms containing x to the left and all other terms to the right.
+3x-13x=+10
We simplify left and right side of the equation.
-10x=+10
We divide both sides of the equation by -10 to get x.
x=-1
