5(x+3)+8

Not necessarily. If the number is 0, then the sum of 8 times the number and -192 is -192.

4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6

5(c+8) or 5c+40

It is: (5+4) times 8 = 72

x(x+8)x^2 + 8x

Suppose the number is x. The sum of the number and two is x+2 Four times the sum is 4(x+2) The number times 8 is 8x 24 less than the number times 8 is 8x-24 4(x+2) = 8x-24 4x+8=8x-24 so 4x = 32 and x = 8

5 + 3 = 8

8n + 2
