The answer is
D.(n+3)!
We just need to simplify the expression
(n+4)!/(n+4) =(n+3)! * (n+4)/(n+4)
(n+4)!/(n+4) = (n+3)! * 1
(n+4)!/(n+4) = (n+3)!
115 divided 23/4 is equivalent to 115 x 4/23= 20
Given the equation <span>-4a/a+4=12/a-11, for sure we need to the solution for a.
</span><span>-4a/a+4=12/a-11
</span>-3a + 4 = 12/a - 11
-3a -12/a = -11 - 4
3a + 12 / a = 15
(3a^2 + 12) / a = 15
3a^2 + 12 = 15a
<span>3a^2 - 15a + 12 = 0
</span>
In order to get a , we need to find the roots.
(3a - 3) (a - 4) = 0
3a - 3 = 0 --> a = 1
a - 4 = 0 -- > a = 4
So the possible solutions for a are 1 and 4.
Answer:
(−∞,∞). no solution
Step-by-step explanation:
The solution of system of equations is: x = 1.6 and y = 1.2
Step-by-step explanation:
Given equations are:
Putting in equation 2
Putting x = 1.6 in equation 2
Dividing both sides by -3
Hence,
The solution of system of equations is: x = 1.6 and y = 1.2
