Answer:
BC:BN=8:3
Step-by-step explanation:
ABCD is a trapezoid and there is a point m which belongs to AD such that AM:MD=3:5.Line "l" parallel to AB intersects the diagonal AC at p and BD at N.
Now, we know that the parallel lines divide the transversal into the segments with equal ratio, therefore, BN:NC=AM:MD
But, BC= BN+NC
Therefore, BC:BN=(BN+NC):BN
⇒BC:BN=(3+5):3
⇒BC:BN=8:3
Notice the picture below
so.. whatever the parabola y= -3x²+k is, will pass over (3,-2) and (-3,-2)
so.. .let us pick say hmmm 3,-2
thus

solve for "k"
Answer:
D.) Elliott has 212 cans, Amelia has 45 cans
Step-by-step explanation:
257 = x + (5x - 12)
257 = 6x - 13
+13 +13
270 = 6x
/6 /6
45 = x (the amount of Amelia's cans)
257 - 45 = 212 (the amount of Elliott's cans)
