Answer:
3 that is the cool answer
if you insist 3 * 3.14 = 9.42
Step-by-step explanation:
the circumference of a circle calculation is 2
your circle r = 27, so circumference = 54
~~~~~~~~~~~~~~~~~~~~~
a circle has 360°
you problem is 20 of the 360
or 20/360 = 2/36 = 1/18
~~~~~~~~~~~~~~~~
your solution is 1/18 * 54 = 3
Answer:
true?
Step-by-step explanation:
That's the last one because you can factor to get
(x + 8)^2 = 36
(x + 8) = +/- 6
Answer:
-18 b^-4= -18/b^4
Step-by-step explanation:
-3b^4(6b^-8)
Combine coefficients
-3*6 = -18
Combine exponents since the bases are the same, x^y * x^z = x^(x+z)
b^4 *b^ -8
b^(4+-8)
b^ -4
Put back together
-18 b^-4
We also know that x^-y = 1/x^y
-18/b^4
