Lin drew a triangle and a dilation of the triangle with scale factor 2

Step-by-step explanation:

Lin drew a triangle and a dilated triangle with a scale factor of .

That means image of the original triangle is smaller than the preimage.

1). Center of dilation will be point A.

   Since, triangle ACB has been reduced to form triangle ADE by a scale factor of

Scale factor = =

AD =

So the center of dilation is point A.

2). Since triangle ADE is half of the triangle ACB, triangle ACB is preimage (original) and triangle ADE is an image after dilation.

step-by-step explanation:

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
