Ohh yess he is!
-9r plus 10r can be written as ( -9r + 10r) and the answer is r.
i have a Johnson MQ-10R it is a 1964 model
-11r
the answer is -10r
The quadratic expression: r2+10r+25 = (r+5)(r+5) when factorised
To combine the expressions (56xy - 35x + 16xry - 10r), you can rearrange and group the like terms. The expression can be rewritten as ( (56xy + 16xry) + (-35x - 10r) ). There are no further simplifications possible since the terms involve different variables and cannot be combined. Thus, the final expression remains (56xy - 35x + 16xry - 10r).
-9r = 20 + rsubtract r from both sides-10r = 20divide both sides by -10r = -2
21
it cant be reduced
The Evinrude outboard, model MQ-10R, would be a 1964 model, 9.5 hp.
5(2r + 5)
1964
