Find two numbers whose sum is 1 and whose difference is -3.
Your answer is:

-1 and 2

Step-by-step explanation:

a = 1st number

b = 2nd number

a + b = 1

a - b = -3

Use the elimination method. You will get

2a = 1 + -3 = -2

a = -2/2

a = -1

a + b = 1

Substitute a for -1

-1 + b = 1

Add 1 to both sides

b = 2

The two numbers are -1 and 2

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
