The first and the third option are correct. if you fail to do the second and last they will take away your house lol
{[5*12]/2}+{[12*25]/2]= 30+150=180m
Answer:
y=-3x2 - 12x+6
, x = -(-12)/2*3 = 2 this one has axis of symmetry x = 2
Step-by-step explanation:
y = 3x² + 12x+6 : x = -12/6 = -2
y = 3x2 - 6x+12
, x = -(-6)/2*3 = -1
y=-3x2 - 12x+6
, x = -(-12)/2*3 = 2 this one
y=-3x2 + 12x+6 , x = -12/2*3 = -2
A positive common factor of 9 and 15 is 3. 9/15 divided by 3/3 = 3/5. It also happens to be the greatest common factor (GCF).
Original Statement: If x = 3, then x^2 = 9 (true)
Converse: If x^2 = 9, then x = 3 (false; this is half the story and x = -3 must be included)
Since the converse isn't completely true, we can't combine the two statements to get a biconditional.
