Replace each "x" in the original equation with (4):
3(4)^2 + 2(4) - 5
= 3(16) + 8 - 5 = 48 + 8 - 5. Can you finish this?
Answer: x=6, y=20
Step-by-step explanation:
Since ΔBCD and ΔTUS are congruent triangles, we can set the sides equal to each other.
y=2y-20 [subtract both sides by 2y]
-y=-20 [divide both sides by -1]
y=20
--------------------------------------------------------------------------------------
3x+32=9x-4 [add both sides by 4, and subtract both sides by 3x]
36=6x [divide both sides by 6]
x=6
They are both going 14 meters per second so therefor they will be the same distance apart the whole time.
