User: Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
Simplify [Q - R] + [S - T]

Weegy: substitute the corresponding expression for each letter (keep the operation sign!) and simplify - > 9) Q+S-T - > (7m+3n)+(n+5)-(m-3n+8)

Weegy: FALSE. A hypothesis can not be proven true unless a highly recognized scientist does an experiment to find evidence that the hypothesis can be supported. (More)

Weegy: The correct response to this problem is answer (d) a - b + c - d + e + f - g User: Take 2y2 - 3y - 5 from y3 - 6y2 + 5y. Select the correct answer.
y3- 2y2+ 3y+ 5
y3- 4y2+ 2y- 5
y3- 4y2+ 2y+ 5
y3- 8y2+ 8y+ 5 Weegy: ((y+1)(2y-5))/(y(y-1)(y-5)) is the answer that I get. Is there another option/answer that you accidentally omitted when you asked this question? (More)
