Are you sure you want ONLY the coefficient of b? If you expand this, you will have b in 3 of 4 terms.
According to Pascal's Triangle, the coefficients of (a+b)^4 are as follows:
1
1 2 1
1 3 3 1
1 4 6 4 1
So (a+b)^4 would be 1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + b^4
Here, you want (3 + b)^4. Here's what that looks like:
3^4 + 4[3^3*b] + 6[3^2*b^2] + 4[3*b^3] + 1[b^4]
Which coeff did you want?
Hello :
<span>4x-5y=13...(1)
x+5y=-3...(2)
(1)+(2) : 5x = 10
x=2
subsct in (2) : 2+5y = -3
5y =-5
y = -1
</span>
First you add 3 and 2 so that is 5 and then you subtract 5 from 9 so the answer is 4.
Answer:
The sum of the three angles of any triangle will always be 180 degrees because when all three angles are put together, they form a straight line.

I did it on Edgenuity
To find the final cost you multiply 35.80 x .07 and you get 2.506 but since its money you round it to $2.51. $2.51 is your sales tax and now you need to add it to the cost of the shirt so 35.80+2.51= $38.31
