Answer:

m < -4

Step-by-step explanation:

divide each side by -3 (since you are dividing by a negative the sign changes from > to <)

m < -4

Solve by completing a square r^2-8r+9

Tanzania [10]

Solving $r^2-8r+9$ by completing a square gives $(r+4)^2-7$

Step-by-step explanation:

We need to solve the equation $r^2-8r+9$ by completing a square

The completing a square method requires: $a^2\pm 2ab +b^2=(a\pm b)^2$

Solving:

$r^2-8r+9\\=(r)^2-2(r)(?)+(?)^2+9$

We need to add and subtract (4)^2=16 to make the equation a complete square

$=(r)^2-2(r)(4)+(4)^2-(4)^2+9\\=(r)^2-2(r)(4)+(4)^2-16+9\\=(r)^2-2(r)(4)+(4)^2-7\\=(r+4)^2-7$

So, Solving $r^2-8r+9$ by completing a square gives $(r+4)^2-7$
