Answer:

Step-by-step explanation:

The area of a triangle is

A=\frac{1}{2}bh and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:

6^2=4^2+h^2\\36=16+h^2\\20=h^2\\h=2\sqrt{5}

That's the height that we will sub into the area formula:

A=\frac{1}{2}(12)(2\sqrt{5})\\A=12\sqrt{5}\\A=26.8

Factor 2m^3-12m^2+18m completely
Nina [5.8K]

Answer:

The answer is A.

Step-by-step explanation:

Firstly, you have to take out the common terms for this expression. In this expression, the common terms ard 2 and m :

2 {m}^{3}  - 12 {m}^{2}  + 18m

= 2( {m}^{3}  - 6 {m}^{2}  + 9m)

= 2m( {m}^{2}  - 6m + 9)

Next you have to factorise the brackets :

{m}^{2}  - 6m + 9

=  {m}^{2}  - 3m - 3m + 9

= m(m - 3) - 3(m - 3)

= (m - 3)(m - 3)

=  {(m - 3)}^{2}

So the final answer is :

2m {(m - 2)}^{2}
