D. 187 m²

Step-by-step explanation:

Alrighty, so this is a standard area problem, the formula for finding the area of a triangle is base x height ÷ 2  so:

34 x 11 ÷ 2 = 187

So the area of the triangle is 187 m²

hope this helps:)

(C) 16

Step-by-step explanation:

Subtract the second equation from the first equation.

9x + 2y^2 - 3z^2 = 132 minus 9y + 2y^2 - 3z^2 = -12

                            9x + 2y^2 - 3z^2 = 132

                            -(9y + 2y^2 - 3z^2 = -12 )  

This will change all the signs of the second equation.

9x + 2y^2 - 3z^2 = 132

-9y - 2y^2 + 3z^2 = +12

You have left 9x - 9y = 144.

Factor out the 9 so you have 9(x - y) = 144

Divide both sides by 9

x - y = 16
