Answer:
It is (almost certainly) the first choice, however, you omitted the actual example there. See below.
Step-by-step explanation:
A counter-example to "All rational numbers are integers" is easy to find - it is any fraction that is reduced to simplest form and its denominator (bottom part) is not 1. Examples: 2/3, 7/5, 11/13 are all not integers but rational numbers and therefore are counter-examples to the statement. The statement is thus disproven. Please check your question - there is a value with the first choice that is likely one such fraction.
The remaining 3 choices to your answer are all not applicable.
Answer:
The dimensions are 7.4m by 15.1 m (to the nearest tenth).
Step-by-step explanation:
Area = length * width
If the width = x then the length = 3x - 7 so
Area x(3x - 7) = 111
3x^2 - 7x - 111 = 0
Using the quadratic formula:
x = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)
x = 7.36, -5.03.
The width must be positive s it is 7.36 m.
The length = 3(7.36) - 7
= 15.08 m.
