1. Resolver las siguientes operaciones con fracciones. Simplificar en caso de ser necesario
a. 6 5 − ( 2 3 + 1 2 ) =
b. ( 3 4 ...
solve find the coefficient of x^5 in (5+8x^2)(3-1/2x)^6
2×4
three day diatary recall
x = x^2 - y^2 -1
y = 2y
x = x^2 + y^2 -1
x^2+y^2-1
2y
5x+4y=-83
3x+3y=-12
35*9
L+V=20
(X*L)+(Y*V)=10
Y=179.49*X/562
(1-Y)=1231.42*(1-X)/562
