Answer:
area = x^2 - 4x
Step-by-step explanation:
a = x(x-4)
a = x^2 - 4x (x times x is x^2, x times -4 is -4x)
It would take five hours for all the bacteria to die. 1000 divided by 5 is 200 so 200×5 = 1000
Answer and Step-by-step explanation:
The length of the rectangle is 3 + w (w represents the width).
<u>The polynomial representing the area of the rectangle:</u>
a (area) = w(3 + w) = w^2 + 3w
A)
a = 1
b = 2
c = 3
d = 1
B)
w = 4
(4)^2 + 3(4) = 8 + 12 = 20
e = 20

well, you already know how to convert from mixed to improper, so let's simply do the division.

Answer:
A
Step-by-step explanation:
The bottom side of the smaller rectangle is marked 10, and the bigger one is marked 20. 20÷10=2, making this a 2:1 scale. Simply multiply the 8 on the right of the smaller rectangle by 2 and you'll get 16, the answer for the similar rectangle.
