Answer the question by finding an equation and determining whether the solutions of the equation are real or non-real. A gardener has 140 feet of fencing to put around a rectangular vegetable garden. The function A(w) = 70w − w2 gives the garden's area A (in square feet) for any width w (in feet). Does the gardener have enough fencing for the area of the garden to be 1,300 ft2?

An equation that can be used is = 0. Because the discriminant is
, the equation has
(select)
, so the gardener
(select)
have enough fencing to enclose an area of 1,300 ft2.

i think the answer is b)

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
