The sum of two numbers is 80. Their difference is 38. What is the product of these two numbers?

The product of these two numbers is 1239.

Step-by-step explanation:

Given that

a + b = 80

a -  b = 38

Add both equation :

a + b = 80

a -  b = 38

2a = 118

a = 59

Put value of a in any 1st equation

a + b = 80

b =  80 - 59

b = 21

Product :

a x b = 59 x 21

        = 1239

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
