Answer:

<h3>X=4</h3>

Step-by-step explanation:

Isolate x on one side of the equation.

19=5x-1

5x-1=19 (First, switch sides.)

5x-1+1=19+1 (Add 1 from both sides.)

19+1 (Solve.)

19+1=20

5x=20

5x/5=20/5 (Then, divide by 5 from both sides.)

20/5 (Solve.)

20/5=4

x=4

Therefore, the final answer is x=4.

svetlana [45]

Answer:

We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Step-by-step explanation:

We know that the perimeter of a rectangle = 2(l+w)

i.e.

P = 2(l+w)

Here

  • 'l' is the length
  • 'w' is the width

Given that the length and width of the playground by a scale factor of 2

A scale factor of 2 means we need to multiply both length and width by 2.

i.e

P = 2× 2(l+w)

P' = 2 (2(l+w))

    = 2P      ∵ P = 2(l+w)

Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Which polynomial equations have -i as one of their roots?
pochemuha
I = sqrt(-1)
i^2 = -1
(-i)^2 = (-i)(-i) = i^2 = -1
(-i)^3 = (-i)(-i)(-i) = (-i)(i^2) = i

use these facts to find which equation is correct if x = -i

i bet on 2,3 or 4
