4
:
(4a + 9) 1
————————————————— - ————— = 0
(a + 3) • (a - 3) a + 3
Pull out like factors :
3a + 12 = 3 • (a + 4)
Equation at the end of step
6
:
3 • (a + 4)
————————————————— = 0
(a + 3) • (a - 3)
3•(a+4)
——————————— • (a+3)•(a-3) = 0 • (a+3)•(a-3)
(a+3)•(a-3)
a+4 = 0
Subtract 4 from both sides of the equation :
a = -4
Answer:
48
Step-by-step explanation:
is basically the horizontal axis.
First, find the integral of x^2-25.
Remember that
integral of a constant is that constant times x.
Also that
to take the integral of a power function, add 1 to the degree and divide by that same degree.
We then get
Evaluate at -3
Then we evaluate at 0
Next, we subtract the the answer then we get
She gotta work 27 hours cuz 344.24/12.75
Answer:
Step-by-step explanation
Note that
Interest is represented by I=1326
The principal is represented by P=47,600
Rate is R =4%
And Time is year
Interest is calculated using the formulae,
I =PRT/100
From the above formulae, time can be calculated as
T=100I/PR
T= 100×1326/(47600×4)
T= 132600/190400
T= 0.6964 years
To convert to days, multiply by 365(since those no of days make a year)
T= 0.6964×365=254 days
This was approximated to the nearest day
Answer is 254 days
