Pls help explain if u can

A dilation (similarity transformation) is a transformation that changes the size of a figure. It requires a center point and a scale factor , k . The value of k determines whether the dilation is an enlargement or a reduction.

In simple words, it's stretching, when you dilate with scale factor of x, means you multiply the previous value with x, say co-ordinates area -2,4, so you do (-2x,4x) to find the co-ordinates after dialation,

Here the scale factor is 3, so the new co-ordinates are,

(-2×3, 4×3) which is A' (-6, 12)

similarly,

B' (12, -3)

C' (-3, -6)

A’(-6;12)

B’(12;-3)

C’(-3;-6)

Step-by-step explanation:

If k is the factor then it means you have to multiply the coordinates of each point ( A, B and C).

So for example:

A’=3xA so when A(x;y) -> A’( 3x;3y)

So you have :

A’(-6;12)

B’(12;-3)

C’(-3;-6)

Then you just have to put them into a scale and rely them three to have your figure .

Hope it helps you.

Have a nice rest of your day :)

the answer to the expression is 83

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
