Answer:
122 times
Step-by-step explanation:
20+102=122
(what is this question lol)
N+2(2n-5)=20
Distribute
n+4n-10=20
Combine like terms
5n-10=20
Add 10 to both sides
5n=30
Divide both sides by 5
n=6
Final answer: 6
Answer:
s(2) = 7.75
Step-by-step explanation:
given the velocity v(t) = t^3
we can find the position s(t) by simply integrating v(t) and using the boundary conditions s(1)=2

we know throught s(1) = 2, that at t=1, s =2. we can use this to find the value of the constant c.

Now we can use this value of t to formulate the position function s(t):

this is the position at time t.
to find the position at t=2



the position of the particle at time, t =2 is s(2) = 7.75
Answer:
(4a + 7b)(16a² - 28ab + 49b²)
Step-by-step explanation:
Use the sum of two cubes to factor
In addition
a³ + b³ = (a + b)(a² - ab + b²)
In subtraction
a³ - b³ = (a - b)(a² + ab + b²)
64a³ + 343b³ = (4a + 7b)(16a² - 28ab + 49b²)
