Answer:
B
Step-by-step explanation:
Two times the quantity of a number minus 12.
Represent the number with the variable y.
The quantity of a number minus 12 is then: (y-12).
Two times this quantity is 2(y-12).
So the answer is 2(y-12), which is B.
Answer:
x - 5
Step-by-step explanation:
(3x-4)(5x^2-2x+6)
15x^3-6x^2+18x-20x^2+8x-24
15x^3-26x^2+26x-24
Answer:
x = -4
Step-by-step explanation:
EM = 5x
ET is half of EM so this statement is true: 5x = 2(3x + 2)
Solve for x.
5x = 2(3x +2)
Distribute 2.
5x = 6x + 4
Isolate x.
-x = 4
Divide -1 out.
x = -4
