if x =4 and y =-3
F =
The equivalent expression for (x + 4)^5 is 
The expression is given as:

To expand the expression, we make use of Pascal triangle, where:
5:= 1 5 10 10 5 1
So, we have:

Evaluate the exponents

Evaluate the products

Hence, the equivalent expression for (x + 4)^5 is

I’m guess you are looking for 751?
1000 = 2*length + 2*wudth
therefore
1000 = 2*150 + 2* width
width = ( 1000 - 300)/2
= 700/2
width = 350
