Answer:
The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30
Step-by-step explanation:
Apparently, we're trying to see if ...
-3(x)(5 -4) + 3(x -6) = -12(x) -6
by evaluating the expressions for x=2:
-3(2)(5-4) +3(2 -6) ?= -12(2) -6
-6 -12 ?= -24 -6
-18 ≠ -30 . . . . . . . . . shows expressions are not equivalent

This demonstration matches the one in the first choice:
The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30
Step-by-step explanation:
59 mi/hr × (5280 ft/mi) × (1 hr / 3600 s) = 86.53 ft/s
Rounded to the nearest whole number, the speed is approximately 87 ft/s.
Answer:
e = 6
Step-by-step explanation:
10e - 2e - 9 = 39
8e - 9 = 39
8e = 48
e = 6
CHECK:
10(6) - 2(6) - 9 = 39
60 - 12 - 9 = 39
39 = 39
I can say that Jared and Nicole are correct because they manipulated the equation right. They can either write the equation as y as a function of x then substitute it to the y in the other equation and solve for x. They can also write the equation as x as a function of y and substitute it to x in the other equation and solve for y. For both solution, they will still obtain the same answers.
