(f + g)(x) = f(x) + g(x) therefore (f + g)(4) = f(4) + g(4)
Answer:
=98m^2
Step-by-step explanation:
11×4=44
9×6=54
44+54=98
=98m^2
Answer: The other dimension can be expressed as
(50 - 2L)/2
Step-by-step explanation: First and foremost, we would let the other dimension be represented by B. Then, the perimeter of a rectangle is measured as L+L+B+B or better put;
Perimeter = 2L + 2B
Where L is the measurement of the longer side and B is the measurement of the shorter side.
In this case the perimeter of the rectangle measures 50m, and this can now be written as
50 = 2L + 2B
Subtract 2L from both sides of the equation
50 - 2L = 2L - 2L + 2B
50 -2L = 2B
Divide both sides of the equation by 2
(50 - 2L)/2 = B
