What figure is a dilation of figure a by a factor of 3? i think the answer is d? (bottom right)

The highlighted one is correct

Step-by-step explanation:

The dilation by a factor of 3 means that each side must increase by 3

The top is a 2 so it becomes a 2*3 = 6

The right is a 3 so it becomes 3*3 =9

The bottom is a 3 so it becomes 3*3 =9

The left is a 6 so it becomes 6*3 =18

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

m∠a is 90°

m∠b is 40°
