The correct answers among the choices presented above are options B and D. Two ways to verify that solutions are correct are done by graphing the equations and see where they meet and by s<span>ubstitute back into both equations. The intersection of the graph signifies the solution. Also, when after substituting the solutions to both equations and they satisfy the equality then it is correct.</span>
Let's use the ratio 3:6 as an example. So 3:6 is the same as 3 over 6, aka 3/6. Divide 3 by 6 and you'd get 0.50. To turn a decimal into a percent, move the decimal to the left 2 times. (If you want to turn a percent into a decimal, you'd move the decimal to the right 2 times.) So then, 0.50 becomes 50%. Hope I helped!!! :-) (You could also multiply the decimal by 100 if you find that quicker/easier)
3x^2+6x^2-4x-8 = 3x^2(x + 2) - 2(x + 2) = (x + 2)( 3x^2 - 2) = 3(x+2)(x -
)(x +
)
Your answer would 699.3 that is it
