Answer:
50.5
Step-by-step explanation:
2xy+2x^2 And we know x=-2.5 and y=-7.5.
In order of operations, exponents come first.
x^2 = -2.5 * -2.5 = 6.5.
6.5*2=13.
2xy + 13
2x=-5
-5*-7.5 = 37.5
37.5 + 13
50.5
Answer:
Step-by-step explanation:
-14rst + 22r²s - 4rs²t = -2 * 7 * rst + 2 *11 *r²s - 2 * 2 rs²t
= -2rs [ 7t -11r + 2st ]
