wait nope I'm right with the area being 336.214 so im not sure why the answers aren't that
7x-55/40-x = 1/2
14x-110 = 40-x
15x = 150
x = 10
GJ = 40-x = 40-10 = 30
Answer:
Below.
Step-by-step explanation:
0.04x20 =0.8 or 80 percent.
80 percent of six thousand is 4800+6000 = 10,800
The two terms are x and 2, thus, x+2 is a binomial. We have to multiply the binomial by itself four times since it is raised to 4th power.
Let us multiply x+2 by itself using Polynomial Multiplication:
(x+2)(x+2) = x^2 + 4x + 4
Taking the result, let us multiply it again by a+b:
(x^2 + 4x + 4)(x+2) = x^3 + 6x^2 + 12x + 8
And again:
(x^3 + 6x^2 + 12x + 8)(x+2) = x^4 + 8x^3 + 24x^2 + 32x +16
The binomial expansion of (x+2)^4 is x^4 + 8x^3 + 24x^2 + 32x +16
