To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Answer:
Step-by-step explanation:
y=3(x-3)(x-4)
=3(x²-4x-3x+12)
or y=3(x²-7x+12)
or y=3x²-21x+36
Answer:
Step-by-step explanation:
v=u+at
38.9=13.2+21.5 t
21.5 t=38.9-13.2
21.5 t=25.7
t=25.7/21.5≈1.195 s
A Exponential growth is the answer
