Answer:
x = abc/ (a+b)
Step-by-step explanation:
x/a + x/b = c
Multiply by ab to get rid of the fractions
ab(x/a + x/b) = abc
bx + ax = abc
Factor out an x
x( b+a) = abc
Divide each side by (a+b)
x ( a+b)/ (a+b) = abc/ (a+b)
x = abc/ (a+b)
Answer:
Its (4x+3)(x+2) 100%
Step-by-step explanation:
Answer:
4(x-1)units
Step-by-step explanation:
In a given rectangle, the length of the rectangle is the shorter side while its breadth is the longer side.
Since we have 2 lengths and 2 breadths in a rectangle, the perimeter of the rectangle will be 2L+2x where
L is the length(shorter side) and x is the breadth (longer side).
According to the question, the shorter side(L) is 2 units less than the longer side(x). Mathematically,
L = x-2
Substituting L = x-2 into the formula of perimeter of a rectangle we have,
P = 2(x-2) + 2x
P = 2x-4+2x
P = 4x-4
P = 4(x-1)
The perimeter of the rectangle will be 4(x-1)units
I believe B But I am not sure I hope this helps . =D
It's not a function because the x value 2 has two y values
