Answer:
Step-by-step explanation:
a. 16b^2c^12-0.25 can be rewritten as follows because it is the difference of two squares:
(4bc^6 - .5)(4bc^6 + .5)
b. 81x^6y^2-0.36a^2
is the difference of two squares, just like (a) (above); its factors are:
(9x^3y - 0.6a)(9x^3y + 0.6a)
Answer:
0.7
Step-by-step explanation:
If we're rounding to one decimal place, we need to round up since it's 0.65.
8+~1-3=4
Explanation-
8-1 is the same as 8+~1 so=7
7-3=4
Answer:
621/87=7.13793103448
Step-by-step explanation:
I divided it and got this answer
We know that
A relationship between two variables, x, and y,<span> is proportional if it can be expressed in the form y/x=k or y=kx</span>
in this problem
k=2
then
y=2x
therefore
the answer is the option
y=2x
