5 roach motels per square yd
A = L * W
A = 7 * 4
A = 21 square yds
so if they set out 5 roach motels per square yd, then they need to set out :
5 * 21 = 105 roach motels <==
8 + 3/4 - 11<span> + </span>1/3<span> = - </span>215<span>/12 = - 17 </span>11/12 = - 17.9166666667; Result written as: improper fraction, mixednumber<span> (also called mixed fraction) and decimal </span><span>number</span>

<h2>
Answer:</h2>
Option: A is the correct answer.
A. Two students are the same age but have different heights.
<h2>
Step-by-step explanation:</h2>
The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .
This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.
Hence, option: A is the correct answer.
Answer:
27, 26
Step-by-step explanation:
27^2 -26^2 = 729 -676 = 53
If the numbers are integers, they must differ by an odd number. For some odd number k, we will have ...
(x +k)^2 -x^2 = 53
2xk +k^2 = 53
x = (53 -k^2)/(2k)
x = 53/(2k) -k/2
The second term is an odd multiple of 1/2. The first term will be an odd multiple of 1/2 only for k=1. For k = 1, we have ...
x = (53 -1)/2 = 26
The two numbers are 26 and 27.
