3x -1
2x 10
(3x-1)(2x+10) = 2(3x-1)(x+5)
Basically what you do is (the ^ arrow meaning exponent)
You take 3.7 + 4.45 x 10^20
Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20
815 x 10^18 = <span>815000000000000000000</span>
Answers B and D are correct. With questions like this, it's fairly easy to divide or multiply to see if the answer is correct.
Answer:
Infinitely many
Step-by-step explanation:
One can substitute any number as the parameter (x), and still get a valid statement, hence there are infinitely many solutions to the equation 4x = 4x.
