Answer:
4x(3x^2-x+5)
Step-by-step explanation:
12x^3-4x^2+20x
=4x(3x^2-x+5)
Answer:
16w^2 - 24w + 9
Step-by-step explanation:
To simplify this, you would use the special product (a - b)^2 = a^2 - 2ab + b^2. We can correlate this with the given term so that,
a = 4w
and
b = 3
Now we just substitute into a^2 - 2ab + b^2
(4w)^2 - 2(4w)(3) + (3)^2
16w^2 - 24w + 9
that's right the way you have it right now in the picture all adds up to 65
The price of fish this week is $3.15 per pound
Step-by-step explanation:
We have to find the total price of 3 pound fish for last week
