Answer:
Step-by-step explanation:
Height h = 4.5 inches
Radius r = 3.4/2 = 1.7 inches
Area of base = πr² = 2.89π square inches
Volume of cylinder = πr²h = 2.89π4.5 = 13.0 cubic inches
120 into 4 give you the right answer
Step-by-step explanation:
let's simply do the multiplications and then compare with the original.
(x-m)² + n
right ?
or is it
![{(x - m)}^{2 + n}](https://tex.z-dn.net/?f=%20%7B%28x%20-%20m%29%7D%5E%7B2%20%2B%20n%7D%20)
let's go for the first.
x² - 2mx + m² + n = x² - 3x
-2mx + m² + n = -3x
fun there we see two things :
-2m = -3
m = 3/2
and
m² + n = 0
(3/2)² = -n
9/4 = -n
n = -9/4
so our transformed expression looks like
(x - 3/2)² - 9/4
Answer:
14r
Step-by-step explanation:
First, you find the perfect squares which 196 and r^2 are both perfect squares. Then, you just simplify them which is 14r.
