Simplify the expression write the expression in scientific notation (5 times 10^7) (6 times 10^4)

You can multiply the coefficients and powers separately:

Solve the first set of parentheses:

Solve the second set of parentheses:

Now the expression can be written as follows:

You can divide 30 by 10, so you can add one to the power for 10^11 and get your

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
