1. If x = 4, what is the value of a=5(2x-3)?
2. If x = 6, what is the value of b=3(-5x+2)?
3. If y = -3, what is the value of c=-2(5y²-2)+4?

1. a = 5 (2x - 3)

a = 5 (2(4)-3)

a = 5 (8-3)

a = 5 (5)

a = 25

2. b = 3 (-5x + 2)

b = 3 (-5(6) + 2)

b = 3 (-30 + 2)

b = 3 ( -28)

b = -84

3. c = -2 (5y² - 2) + 4

c = -2 (5(-2)²-2) + 4

c = -2 (5(4)-2) + 4

c = -2 (20-2) + 4

c = -2 (18) + 4

c = -36 + 4

c = -32
