Which statements are true about the rules of multiplication for signed numbers? check all that apply. the product of two negative integers is positive. the product of two integers with different signs is positive. if two numbers are the same sign, then the product is positive. the product of a positive and a negative is negative. if the signs of two integers are different, then the product is positive.

The product of two negative integers is positive. (-a) *(-b) = ab  True

The product of two integers with different signs is positive. (-a) (b) = -ab  False

If two numbers are the same sign, then the product is positive.

a*b = ab   -a * -b = ab   True

The product of a positive and a negative is negative.

-a * b =- ab    a * -b =- ab      True

If the signs of two integers are different, then the product is positive.

-a * b =- ab    a * -b =- ab      False

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
