Question

If x equals 6 + Y equals -2 what is the value of 3x y + 2x square - y to the Third

Answer 1

If x equals 6 and Y equals -2 what is the value of 3x y + 2x square - y to the Third:

Plug in 6 for x and -2 for y:

3(6)(-2) + 2(6)^2 - (-2)^3

Using the correct order of operations, you should begin with the exponents. Six squared is 36 and -2 cubed is -8. Therefore:

3(6)(-2) + 2(36) - (-8)

Next, multiply, which yields:

-36 + 72 + 8

Finally, add/subtract from left to right, and your answer is 44.
