Answer:
1.46666666667
Step-by-step explanation:
calculator
we have the expression
Evaluate for x=-4/5 and y=1/3
substitute the values of x and y in the given expression
the answer is 32/15
P = L + L + w + w
72 = 2(L) + 2(L-4)
Distribute
72 = 2(L) + 2(L) - 8
Add like terms
72 = 4(L) - 8
Subtract 8 from both sides
64 = 4(L)
Divide both sides by 4
16 = L
The length is 16. Now substitute that in the equation for finding w.
w = L - 4
w =
Answer:
Explanation:
In the first example the division results in a radical, not a polynomial.
The remaining examples are not counter-examples (they do result in a polynomial)
