−4(7b+3)+24b−8

Answer 1

Expanding the expression:

-4(7b+3)+24b-8

-4 * 7b = -28b

-4 * 3 = -12

-28b - 12 + 24b - 8

(24b - 28b) + (-12 - 8)

-4b - 20

Therefore, -4(7b+3)+24b-8 simplifies to -4b - 20.

Answer 2

2(3v+9)−14−6(−5v−4)

Answer 3

Expanding the expression:

2(3v+9)−14−6(−5v−4)

2 * 3v = 6v

2 * 9 = 18

6v + 18 - 14 -6(-5v-4)

-6 * -5v = 30v

-6 * -4 = 24

6v + 18 - 14 - 30v - 24

(6v - 30v) + (18 - 14 - 24)

-24v + (-20)

Therefore, 2(3v+9)−14−6(−5v−4) simplifies to -24v - 20.

Answer 4

−15+45(15e−10)−10e

Answer 5

Expanding the expression:

-15+45(15e−10)−10e

45 * 15e = 675e

45 * -10 = -450

675e - 450 - 10e - 15

(675e - 10e) + (-450 - 15)

665e - 465

Therefore, -15+45(15e−10)−10e simplifies to 665e - 465.
