Answer:
12
Step-by-step explanation:
Start by expanding the expression:
4(3x+5)
Distribute the 4 to each of the numbers in the parentheses
12x+20
The coefficient of x is basically what is being multiplied by x. In this scenario, we can expand 12x to be...
12*x
Which means that the coefficient of x is 12

Answer:
2
Step-by-step explanation:
To find the scale factor of a dilation, we first find two corresponding sides. For example, the leftmost side of the black shape corresponds with the leftmost side of the blue shape. The side on the black shape measures 2 units while the side on the blue shape measures 4 units.
Now, we divide the length of the side taken from the figure by the length of the side taken from the original shape.
4/2=2
Therefore, the scale factor of the dilation is 2.
