Which of the following are solutions to the equation below? (4x-1)^2=11

1 answer:

4 0

You have to use the quadratic formula to solve this. when you do, you get x values of 1.079 and -.5791. You did not provide choices but that's what it comes out to.

HELP MEE PLZZZZ I DON'T UNDERSTAND THIS

Damm [24]

Answer: Choice D. $6.44 \times 10^{-4}$

========================================================

Work Shown:

We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents

This is what the steps could look like

$\left(9.2 \times 10^{-9}\right)\times\left(7 \times 10^{4}\right)\\\\\left(9.2\times7\right)\times\left(10^{-9} \times 10^{4}\right)\\\\\left(64.4\right)\times\left(10^{-9+4}\right)\\\\\left(6.44\times 10^{1}\right)\times\left(10^{-5}\right)\\\\6.44\times\left(10^{1}\times 10^{-5}\right)\\\\6.44\times\left(10^{1+(-5)}\right)\\\\6.44\times 10^{-4}\\\\$

The final result is in scientific notation as the coefficient c is restricted such that $0 \le c < 10$
