3m2 plus 6m2 divide by 3m?
3 meters. 9m2/3m Divide both sides by 1m 9m/3 Simplify 3m
What does m2 mean?
Square Metre ...... eg 3m2 = 3 square metres
How can you factor by groupig 4 3xy-6y-2x?
(3m2+4n)3
A child needs an area of 3m2 how many children can be in a building that is measured 30m by 80m?
800
How do you factor 3m2 plus 32m plus 64 and please explain?
It's not very scientific, but I usually solve these things with a mixture of common sense and trial and error. Call it educated guessing. The 3 in 3m2 only has two factors, so your brackets will start out with 3m and m. (3m )(m ) All of the operational signs are pluses. The brackets will have them too. (3m + )(m + ) Now you're looking for factors of 64 that will solve the equation. 64 only has four factor pairs, so it won't take long to try them all. 64 and 1 won't work. 32 and 2 won't work. 16 and 4 won't work. (3m + 8)(m + 8) Check it using the FOIL method. (First, Outside, Inside, Last) 3m x m = 3m2 3m x 8 = 24m 8 x m = 8m (24m + 8m = 32m) 8 x 8 = 64 (3m + 8)(m + 8) = 3m2 + 32m + 64. It checks.
