What is the product? -4. [8/-1/-5/9]

- 32, 4, 20, and - 36

Step-by-step explanation:

We have to find the product of -4 with 8 / - 1 / - 5 / 9.

Now, the product of - 4 and 8 is = - 32  

{Since the product of a positive number and a negative number is always negative}

The product of - 4 and -1 is = 4

{Since the product of two negative numbers is always positive}

The product of - 4 and - 5 is = 20

The product of - 4 and 9 is = -36

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

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
