Simplify QP. please help

I think the ans is

=Square root(my keyboard doesn't have the square root) b^2+(-c+a)^2

Step-by-step explanation:

So the point of Q, 0 is the x1, -a is the y1, point P, b is the x2, while -c is y2.

So, you just sub the points of Q and P in the distance formula, then you will find it

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

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
