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

A. m - 2n - 2
B. -m + 2n - 2
C. -3m - 4n + 14
D. 3m - 4n + 14

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
