What is the least common denominator of 4/x * -4/2x^2?

Vanyuwa [196]

The least common denominator would be 2x^2
that is because you would have to multiply the first fraction by 2x
but you can't just somehow simplify 2x^2, it wouldn't be right
4/x * -4/2x^2
2x*4/(2x*x) * -4/2x^2
8x /2x^2 * -4/2x^2
Then you would complete it

Hope this helps :)

A service station will be built on the highway, and a road will connect it with cray. How long will the new road be?

zysi [14]

Answer: 4.6 mi

Step-by-step explanation:

Suppose the points A, B, C and S shows Alba, Blare, Cray and Service station respectively,

Then, We have to find out the line segment CS = x = ?

Now, In the triangles ACB and CSB,

$\angle ACB\cong \angle CSB$ ( Right angles )

$\angle ABC\cong \angle CBS$ ( Reflexive angles )

Thus, by AA similarity postulate,

$\triangle ACB\sim\triangle CSB$

By the property of similar triangles,

$\frac{AB}{CB}=\frac{AC}{CS}$

$\implies \frac{13}{5}=\frac{12}{x}$

$\implies 13x=5\times 12$

$\implies 13x = 60$

$\implies x =\frac{60}{13}=4.61539\approx 4.6$

Hence, the approximate length of the new road = 4.6 miles

The equation for the pH of a substance is pH = –log[H+], where H+ is the concentration of hydrogen ions. Which equation models t

Zanzabum

Answer: [H+] = 10^-7.2

Step-by-step explanation:

Given that the PH of the solution = 7.2

Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have

10^ -pH = H+. with pH of 7.2,

Thus the answer to this problem is

[H+] = 10^-7.2

Levi's mom gave him $30 so he can go to the movies.He used 1/5 of the money to pay for his movie ticket.He spent 1/3 of what he

kolbaska11 [484]

If Levi has $30, and he spends 1/5 of it on his movie ticket, we can figure out how much 1/5 is by dividing 30 by 5.

30 divided by 5 = 6

Now Levi has $6. He than spends 1/3 of that on popcorn. We can divide 6 by 3.

6 divided by 3 = 2

Levi is left with $2.
