Answer:
It would be distributive property
Step-by-step explanation:
Because you have parenthesis and you need to distribute that 2 to everything in the parenthesis and you will get 2x+6 because 2(x)=2x and 2(3)=6 and when you put those together you get 2x+6
Hope this helps! Sry if I get it wrong! :)
The solution is (-4,3)
-3x-3y=3
y=-5x-17
so find the y in the first equation in terms of x
-3x-3y=3
-3y=3x+3
y=-x-1
then set the two equations equal to each other
y=-x-1
y=-5x-17
-x-1=-5x-17
4x=-16
x=-4
now put the x into one of the equations
-3(-4)-3(y)=3
12-3y=3
-3y=-9
y=3
so the solution is (-4,3)
to check it, put the points into equations and see if they're correct
-3(-4)-3(3)=3
12-9=3
3=3 correct
3=-5(-4)-17
3=20-17
3=3 correct
10 1/4 / 151 3/16 = 4/59
Have a great day :)
Answer:
2.1 m
Step-by-step explanation:
The gutter is in the shape of a cylinder.
Its volume is 20 liters and its diameter is 11 cm (0.11 m).
Its radius is half of its diameter => r = 0.055 m.
The volume in cubic metres:
1 litre = 0.001 cubic metres
20 litres = 20 * 0.001 = 0.02 cubic metres
The volume of a section of guttering is given as:

where h = length of the guttering
Therefore:

The length of the section of guttering is 2.1 m long.
Is there a picture with it?
