Answer:
Step-by-step explanation:
3x² -2 =3*(-3)²-2=3*9 - 2
= 27 - 2
= 25
I believe you have 6 bacteria 120 divided by 20 is 6 so
<span>volume = l x w x h</span>
<span> to increase volume by 3 you would have 3*l*w*h </span>
<span>so 3*l*w*h= l*2*w* x *h ( x is the scale factor)
</span><span> cancel out the l w and h on both sides
3 = 2x
Divide both sides by 2
x = 3/2 = 1.5
</span><span> the height should increase by a factor of 1.5</span>
It's just the slope formula.
y = mx + b
The "m" is the slope.
The "b" is the y-intercept.
The y and the x don't change.
Girl with that what is you saying
