Use the equation for the area of a triangle:

where A = area, h = height of the triangle, and b = base of the triangle.
You know that h=18m and A=99

. Plug those values into the equation and solve for b, the base.
The base is 11m long.
I believe it is numbers 184x√2
Hello there,
The equation that we have to factor is as follows:
2x² + 3x - 54
In order to factor this we first multiply (-54) by 2 and try to find two factor pairs that can be add up to 3.
For this we would use 12 * -9 which gives you -108 when multiplied and when added you would get 3.
2x² + 12x - 9x -54
2x(x + 6) -9(x +6)
(2x - 9) (x + 6)
Now the factor pairs would be: (2x - 9)(x + 6)
Hope I helped,

Can you take a more clearer picture thx
