Answer:

Pretty sure it's ab + ab

Step-by-step explanation:

Taking the test myself.. if it needs to be even for all integers and it doesn't give us numbers for a or b then ab + ab is the only "even for all integers"

Translate this problem to an equation and solve. The area of a patio is 72 square feet. The length of the patio is 1 foot longer
Inessa05 [86]
A = LW
A = 72
L = W + 1

72 = W(W + 1)
72 = W^2 + W
W^2 + W - 72 = 0
(W + 9)(W - 8) = 0

W + 9 = 0
W = -9......extraneous solution...does not work here

W - 8 = 0
W = 8 <==

L = W + 1
L = 8 + 1
L = 9

so the width (W) is 8 ft and the Length is 9 ft

Please show steps in how to solve the problem 2 1/6 - 1 5/6
IgorC [24]

Answer: 2/6 or 1/3

Step-by-step explanation: First you want to change the two fractions to improper fractions, so 2 1/6 will become 13/6 and 1 5/6 will become 11/6.

Using those improper fractions, you subtract the numerators since the denominators are the same, so 13 - 11 is 2 for the numberator.

2/6 can be simplified into 1/3 by dividing the numerator and denominator by 2.

The manager of a warehouse would like to know how many errors are made when a product’s serial number is read by a bar-code read
maw [93]
<span>In order to determine the total number of errors that were made by the bar code scanner, we first have to calculate how many total scans were made. Because there were six items scanned 1,000 times each, there were 6,000 total scans made. Next, we have to add up the total number of errors made by each item (36+14+21+39+11+2). As a result, there were a total of 123 errors made during the 6,000 scans.</span>
