Answer:

Ok so first, divide the figure into 2 triangles ABC and ADC

Then, find the area of triangle ABC, base being 10 (5+5) and height being 4

= 1/2 * bh

= 1/2 * 10 * 4

= 20 sq. units

For 2 triangles, 20 * 2 = 40 sq. units

Noah says that 9x - 2x + 4x is equivalent to 3x, because the subtraction sign tells us to subtract everything that comes from af

Agree with Elena. Noah is wrong. If it is 9x-(2x+4x) then it equals to 3x.

I don't like these computer choice thingies. It detracts from the math.

$-x - 2y = 7$

$5x - 6y = -3$

If we want to eliminate x we multiply the first equation by 5 then add it to the second:

$-5x - 10y = 35$

$5x - 6y + (-5x - 10y) = -3 + 35$

$-16y = 32$

OK, that's how it's done. Reading through the choices, that's choice D.
