Answer:

X = -2 and 4

Step-by-step explanation:

Move all of the terms to one side and set the equation to 0:

2x^2-14x+40-3x^2+16x-32 = 0

Then combine all like terms which would look like the following:

-x^2 + 2x + 8=0

Change the signs on both sides of the equation:

x^2 - 2x - 8 =0

Write -2x as a difference:

x^2 + 2x - 4x -8 = 0

Factor the expression:

x(x+2) x 4(x+2)=0

Factor out x+2 from the equation:

(x+2) (x-4)=0

Split into classes and then find the answer from there:

x+2=0

x-4=0

Esther has a farm.
Gnesinka [82]

Here, we are required bro determine how many worker Esther needs to employ to pick the same 600kg of onions in 3 hours as compared to 4 hours from last year.

This year, she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.

According to the data given, the total quantity of onions to be picked still remains 600 kg as from last year, only that she needs it done in 3 hours now.

Therefore,

  • Since 24 workers finished the work in 4 hours,
  • This means that 96 workers are needed to finish the work in 1 hour( from 24×4 = 96).

Therefore, since the work needs to be done in 3 hours this year, This means that it can be shared between X no. of workers.

  • Where X = 96/3= 32

Therefore, this year she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.

Answer:

Distance(PQ)=\sqrt{113}

Step-by-step explanation:

In coordinate geometry distance between the two points can be find by using the distance formula:

For two points :

            (x_1,y_1)\\and \\(x_2,y_2)

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

For points: P(3,-1) and Q(-5,6)

Distance (PQ):

                    =\sqrt{(-5-3)^2+(6-(-1))^2} \\\\=\sqrt{(-8)^2+(6+1)^2}\\\\ =\sqrt{(-8)^2+(7)^2} \\\\=\sqrt{64+49}\\\\Distance(PQ) =\sqrt{113}\\\\
