When do you factor out a negative?

8 answers · 2 days ago
Best answer: If the term with an exponent 2 or more is negative factor out -1 as the expression becomes much easier to factor.

Best answer: Every time, sometimes twice per answer. Seems to vary with individual, for some unknown reason. I'm starting to hate storefronts, traffic lights, motorcycles, cars, hills, etc.

.29 for me.

A rectangular tank will have a square base and its volume will be 125 cubic meters. The cost per square meter for the base is $ 8.00 and for the sides it will be $ 4.00. Find the dimensions of the deposit for the cost of the material is the minimum!

Best answer: They cannot be compared, because infinity is not a number.

Best answer: There will be one even number (2) in the sum, then the remaining 1,999,999 primes will be odd (because of they were even they'd have 2 as a factor and not be prime). The sum of an odd number of odd numbers will be odd. Adding 2 to that will not change the parity, so the final sum will still be odd.

I know that there is 7 then 7 and a half but what is after that and after that just before 8? Please help

How do you round 4.495?

Best answer: The only thing that matters is the next digit. I assume you are rounding to the nearest whole number: 4.|495 The only thing that matters is the next digit immediately after the place you are rounding to: 4.|495 ....^ If that is *5* or higher, you round up, otherwise you do not. In either case, drop everything... show more

Solve for n. Verify your answers. [(3^n)^n x (3^n)^-1] / 81 = 1 The answer is n= -1, 4 but I don t know how to get to it?

Two buildings are 35m apart. From the top of the shorter building, the angle of depression to the base of the other is 47° and the angle of elevation to the top of it is 21°. Find the height of the taller building.

Best answer: Do you mean 2 + 3 = 5...odd 3 + 5 = 8 ..even 5 + 7 = 12... even 2 + 3 + 5 + 7 = 17...odd. So if you add ALL primes then because of 2 being the only even will always be odd.
