39 foot into 3 pieces
one is 13 feet
 the other pieces add up to the remaining wire
 which is 39-13=26 so
 the two remaining pieces are x and y
one must be 2 less than 3 times the other
 x must be 2 less than 3 times the y
x=-2+3y
 x=3y-2
 x+y=remaining=26
 26=x+y
 x=3y-2
 subsitute
 26=3y-3+y
 add like terms
 26=4y-2
 add 2 to both sides
 28=4y
 divide by 4
 7=y
 subsitute
 7+x=26
 subtract 7
 x=19
 19>7
 7 feet is the legnth of the shorter piece

there would be a 99% chance of a red marble being pulled out or even a 1% chance.

because of their being five green marbles and six red there is always a chance you could pull out any one of the colors.

but i believe that both of the answers are 1/2

but im not 100% sure

Choose the property used to rewrite the expression.
Alex73 [517]

The property used to rewrite the given expression is product property.

Answer: Option A

<u>Step-by-step explanation:</u>

Given equation:

                          \log _{2} 10+\log _{2} 4=\log _{2} 40

The sum of the two logarithms of two quantities (on the same basis) corresponds to the logarithm of their product on the same basis. The product log is equal to the log’s sum of the factors.

                                \log _{b}(x \times y)=\log _{b} x+\log _{b} y

There are several rules that you can use to solve logarithmic equations. One of these guidelines is the logarithmic products rule that you can use to differentiate complex protocols in different ways. Different values that can be valuable are the quota principle and the logarithm rule. The logarithmic products rule is essential and is regularly used in analysis to control logs and simplify baseline conditions.
