Set up a proportion:
5/200 = 7/x
Cross multiply:
200 * 7 = 5 * x
1400 = 5x
Divide 5 to both sides:
x = 280
(-7) negative 7 i had some of these questions in pre-algrebra

198 is the answer ok ok ok
= x^2 - y^2/6 * 12/(x-y)
= 6x^2 -y^2 * 72/(x-y)
= 6x^2(x-y) -y^2(x-y) * 72
= 6x^3 - 18x^2 -xy^2 + y^3 * 72
= 432x^3 - 1296x^2 -72xy^2 + 72y^3
