FACTOR
x^2 + 10× - 2400 = 0​

x= -5 + 5, x= -5 - 5

Step-by-step explanation:

Since this quadratic is set to zero, we can use the quadratic formula to solve this.

x^2 + 10x - 2400 = 0​

Quadractic formula =  x= -b +- /2a

For this equation:

a= 1, b=10, c=-2400

Plug these numbers into the equation and solve.

x= -10 +- )/2(1)

x= -10 +- /2

x= -10 +- /2

x= -10 +- /2

x= -10 +- 5 * 2/2

x= -10 +- 10 / 2

Divide by 2.

x= -5 +- 5

x= -5 + 5 or x= -5 - 5

51-50

step-by-step explanation:

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
