Under a dilation, triangle xyz where x(4, 7), y(-3, 8), and z(-2, -1) becomes triangle x’y’z’ where x’(12, 21), y’(-9, 24), and z’(-6,-3). what is the scale factor for this dilation?

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
