Your teacher makes the following statement, “ the set of whole numbers is closed under multiplication, but the set of irrational numbers is not closed under multiplication. “ ( even if you only answer 1 that’d be great ) (a) what does it mean for a set of numbers to be closed under multiplication? (b) what example could you use to support the statement that whole numbers are closed under multiplication? explain (c) what example could you use to support the statement that irrational numbers are not closed under multiplication? explain.

step-by-step explanation:

this is not a question

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
