Practice solving quadratic equations.

Dennis_Churaev [7]

In order for the equation to be true, one of the factors on the left has to equal zero

So, 2x-3=0 or x-4=0 (the 3 on the left for multiplication doesn’t affect the possible answers for x)

Once you solve them, you conclude that x has to be 4 or 3/2.

What is the ratio of the least common multiple of 180 and 594 to the greatest common factor of 180 and 594

kherson [118]

Answer:

Step-by-step explanation:

least common factor of 180 and 594 is 5940.

greatest common factor of 180 and 594 is 18.

so, the ratio of the least common factor to the greatest common factor will be;

ratio = $\frac{5940}{18}$

= 330

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 $0 \le c < 10$
