I think the decrease is $615.
She would have $7585 left in her account at the end of the year.
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
Check the picture below.
now, based on the provided information, we know the hexagon and triangle are regular polygons, <u>equal sides and equal angles</u>, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.
now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.
if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a <u>full revolution</u> will be 360°, so the remaining angle in green there must be 360° - 120° - 136° = 104°, and her twin at vertex J is also 104°.
