What is the answer for-10x - 5 = -8x + 11
OLga [1]

Answer:

In order to solve this equation, you have to isolate the x and set it equal to a number. I chose to add 8x to both sides, making it -2x - 5 = 11. Then add 5 to both sides, making it -2x = 16. Divide both sides by -2 to get x = -8. -8 is your answer. Hope this helps!

The length and width of a rectangular room are measured to be 3.955±0.005m. Calculate the area of the room and its uncertainty i
Margarita [4]

Answer:

The area of the room and its uncertainty in square meters is:

15.642±0.040 m^2

Step-by-step explanation:

We know the area of a rectangular room is the multiplication of the length and width:

Area= 3.955m*3.955m\\Area= 15.642 m^2

Now we need to know the uncertainty, the uncertainty of a multiplication is:

\frac{δ_a}{|Area|} =\frac{δ_L}{|L|}+\frac{δ_W}{|W|} (1)

δ_A: Area uncertainty

δ_L: Length uncertainty

δ_W: Width uncertainty

A: Area of the room

L: Length

W: Width

Clearing the uncertainty of the area:

δ_A=(\frac{δ_x}{|x|}+\frac{δ_y}{|y|})*Area (2)

δ_A=(\frac{0.005}{|3.955|}+\frac{0.005}{|3.955|})*15.642 m^2

δ_A= 0.040 m^2

The area of the room and its uncertainty in square meters is:

15.642±0.040 m^2
