Question

Simplify 2(3v+9)−14−6(−5v−4) .

Answer 1

−15+45(15e−10)−10e

Answer 2

Using the distributive property, we have 2(3v+9) = 2(3v) + 2(9) = 6v + 18.
Similarly, -6(-5v-4) = -6(-5v) - 6(-4) = 30v + 24.
Now, our expression becomes 6v + 18 - 14 + 30v + 24.
Combining like terms, we have (6v + 30v) + (18 - 14 + 24) = 36v + 28.
Therefore, the simplified expression is 36v + 28.

Answer 3

Using the distributive property, we have 45(15e-10) = 45 * 15e - 45 * 10 = 675e - 450.
Now, our expression becomes -15 + 675e - 450 - 10e.
Combining like terms, we have (-15 - 450) + (675e - 10e) = -465 + 665e.
Therefore, the simplified expression is 665e - 465.
