Write an expression that can be used to multiply 6 x 198 mentally? please answer thanks!
valkas [14]
-6 x 2 + 6 x 200. Since you want to find out 6 multiplied by 198 the easiest way (for me) would be to round it and then substract 12 since 200-198 is equal to 2 and 6 x 2 is equal to 12

Combining like terms
MAXImum [283]

Combine like terms to simplify an expression. For example, all terms with the variable x can be combined into one term. All constants can also be combined.

1) -4x - 10x = -14x

2) -r - 10r = -11r

3) -2x + 11 +6x = 4x + 11

4) 11r - 12r = -r

5) -v + 12v = 11v

6) -8x - 11x = -19x

7) 4p + 2p = 6p

8) 5n + 11n = 16n

9) n + 4 - 9 - 5n = -4n - 5

10) 12r + 5 + 3r - 5 = 15r (the 5 and -5 cancel each other out)

11) -5 + 9n + 6 = 9n + 1

What is the factorization of the following trinomial? 15x2 - 44x - 36
BartSMP [9]
15x^2-44x-36

=(15x^2+10x)+(-54x-36)

factor out  5x from 15x^2+10x  = 5x(3x+2)

Factor out -18 from -54x-36 =  -18(3x+2)

=5x(3x+2)-18(3x+2)

Factor out common term (3x+2)

= (3x+2)(5x-18)

hope this helps!
