Explain how you know whether to add or subtract when you use the distributive property to multiply

Distributive property of multiplication has two expressions:

1.

2.

If you use these formulas from the left side to the right side, you should see for the sign in the brackets: "+" - use addition, "-" - use subtraction. If you use these formulas from the right side to the left side, you should also take into account sign between and : for "+" - use addition in brackets and for "-" - use subtraction in brackets.

The correct answer is:

We treat the addition or subtraction signs inside the parentheses as positive and negative signs and follow our integer rules.

Explanation:

Take for example -3(x+y). The distributive property tells us to take -3*x + -3*y; we have a positive multiplied by a negative, which is a negative, and another positive multiplied by a negative, which is again a negative. This gives us -3x+-3y, or -3x-3y.

If we consider the sign of the value outside the parentheses as well as the signs of those inside, we can be sure to use the write operation sign.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
