Answer:
3u(u - 2)
Step-by-step explanation:
greatest common factor: 3u (both are divisible by 3, and include the variable u)
factor: 3u^2/3u = u; -6u/3u = 2
new polynomial: 3u(u - 2)
Answer: 10x³
<u>Step-by-step explanation:</u>
n=0 1
n=1 1 2 1
n=2 1 3 3 1
n=3 1 4 6 4 1
n=4 1 5 10 10 5 1
The second term of the expansion is: 5(a)³(b)
= 5(x)³(2)
= 10x³
Answer:
time = 28 years
Step-by-step explanation:
Given,
principal amount = $10,000
rate = 4%
total amount = $30,000
According to compound interest formula
where, A = total amount
P = principal amount
r = rate
t = time in years
so, from the question we can write,
by taking log on both sides, we will get
=> log3 = t.log(1.04)
=> t = 28.01
So, the time taken to get the amount from 10000 to 30000 is 28 years.
Answer:
29t + 24
Step-by-step explanation:
5(5t + 6) + 2(2t - 3)
Open Parentheses first.
5* 5t = 25t
5 * 6 = 30
25t + 30 + 2(2t - 3)
Open others
2 * 2t = 4t
2 * 3 = 6
25t + 30 + 4t - 6
Match like terms
29t + 24
3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
