Answer:

344

Step-by-step explanation:

Um..... sorta confusing, but I think you are only allowed to increase by 10 each time, so then you need to add 20 to make 344, where the units digit and tens digit are the same

Anni [7]

Answer:

point B

Step-by-step explanation:

isolate the x to solve for x:

=> x = 1 - $\frac{3}{4}$

=> x = $\frac{1}{4}$

point B=> the half of $\frac{1}{2}$ is $\frac{1}{4}$ => $\frac{1}{2}$ x $\frac{1}{2}$ = $\frac{1}{4}$

What is the second term in the binomial expansion of (2r-3s)12?

Reptile [31]

$(a+b)^n=\displaystyle\sum_{k=0}^n\binom nka^{n-k}b^k$

where $\dbinom nk=\dfrac{n!}{k!(n-k)!}$ . The second term of the expansion occurs when $k=1$ .

So the second term of the expansion of $(2r-3s)^{12}$ is

$\dbinom{12}1(2r)^{12-1}(-3s)^1=12(2r)^{11}(-3s)=-73728r^{11}s$
