Answer:
12.375
Step-by-step explanation:
Length x Width
L x W
4.5*2.75 = 12.375
Answer:
128 squared feet
Step-by-step explanation:
A=2(wl+hl+hw) is the formula if you multiply the edges the add then twice because of the 3d shape you get 128.
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?
