Solve x^2 - x ≥ 0. a) ] − ∞, −2 [ ∪ ] 3, ∞ [ b) ] − ∞, 2 [ ∪ ] 3, ∞ [ c) ] − 2, 3 [ d) ] − 1, 1]

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

i belive those are the ones that are under 90 degreese.

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

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
