Identify the factors of x2 + 36y2. (5 points)
prime
(x + 6y)(x − 6y)
(x + 6y)(x + 6y)
(x − 6y)(x − 6y)

Factors can be checked by reverse method, check the choices and find which prime matches the given:
Let us try the first item:
(x + 6y)(x-6y)
=x²-6xy +6xy -36y²
=x² - 0xy - 36y²
= x² - 36y²

Let us try the second item:
(x+6y)(x+6y)
=x² + 6xy +6xy + 36y²
=x² + 12xy + 36y²

Let us try the third item:
(x-6y)(x-6y)
=x²-6xy-6xy+36y²
=x² - 12xy +36y²

No correct factors from the given choices.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
