Number 5 is x = 18 and number 6 is x = -2
Answer:

Step-by-step explanation:
Let's start by writing what we know in mathematical terms.
A rectangle has a length that is 3 more than twice its width, means:

Now all we have to do is solve for one of these values. I'll choose W.
Rewrite the equation:

Input that information into our second equation and solve:

Find the two W values by factoring the equation (note that the Width can't be negative because you can't have a negative rectangle):

We pick the positive value 8 and plug it into our original equation to find Length:

Finally, after all that, we can use the formula of a perimeter using our newly found Length and Width values (remember not to forget "ft^2" when we get our answer):

Since a week is 7 days you have to multuply 7*3/4
Turn 7 into a fraction
Step-by-step explanation:
The GCF of these numbers is 3 i did found it by prime Factorization 12 prime Factorization is 3x2x2 and for 12 is 3x3x3 so 3 it is the same of both so us it and bye have a good day
(6x^-2)^2(0.5x)^4 = (6^2)(x^-2(2))(1/2)^4(x^4) = 36x^-4(1/16x^4) = (36/16)x^(-4+4) = 9/4
