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!
Y+y-3 is the expression need to find the triangle's area
Answer:
The area of the room and its uncertainty in square meters is:
15.642±0.040 
Step-by-step explanation:
We know the area of a rectangular room is the multiplication of the length and width:
Now we need to know the uncertainty, the uncertainty of a multiplication is:
(1)
: Area uncertainty
: Length uncertainty
: Width uncertainty
A: Area of the room
L: Length
W: Width
Clearing the uncertainty of the area:
(2)
The area of the room and its uncertainty in square meters is:
15.642±0.040
Answer:
Step-by-step explanation:
Sin 45 equal to 1 by root 2
Then
1 by root 2 is equal to x by 11 root 2
Then
11 root by root 2 equal to x
Then answer will be 11
false
the slope of -1 and the slope of -1 are parallel, not perpendicular
