Simplify 12edf – 13def. State a property that you can use.
Anna [14]

Answer:

-def. In multiplication, the order doesn't matter.

Step-by-step explanation:

A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.

3 * 2 = 6

2 * 3 = 6

5 * 2 * 3 = 30

2 * 3 * 5 = 30

3 * 2 * 5 = 30

Thus,

edf, or

e * d * f

is the same as def,

d * e * f

e * d * f = d * e * f

edf = def

Thus, 12edf is the same as 12def. We can put this in our expression:

12edf - 13def

12def - 13def

Now, we can see that this will equal -1def or -def

12def - 13def

-1def

-def

Answer: -def. In multiplication, the order doesn't matter.

B) The graph of y = x^2–2x + 5 is
8090 [49]

Better yet, let y = 6 and solve for x.

6 = x^2 –2x + 5

Now solve for x.
