A force of $20$ newtons will stretch a spring $5$ centimeters. What is the total number of centimeters that a force of $60$ newt
Aleksandr-060686 [28]

Answer:

Step-by-step explanation:

Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:

\frac{N}{cm}:\frac{20}{5}=\frac{60}{x} and cross multiply:

20x = 300 so

x = 15 cm

Does someone know this? :)
kvv77 [185]

Answer:

Your answer would be

- 2/25 x^3a^3

Or vice versa with the variables

- 2/25 a^3x^3

TO solve it’s pretty simple if you do it correctly.

So with all the variables in the two multiples, you can find a way to combine them

So ignoring everything else you’d get

a^2x * x^2a

You we can see the difference,

theres a^2 and a

Whilst there is also x^2 and x

Now we can combine them

a^3 x^3

Now we can do the normal multipacation with the fraction

2/5 * - 1/5 which is -2/25

Now combine

ANd you got it :D

6. What is the greatest common factor of the following expression? *<br> 15y3 – 40y
Nady [450]

Answer:

I'm not sure what 15y3 is, but I'll take a guess.

If the only numbers are 15, 3, and -40, then the greatest common factor is 1.

If the only numbers are 15 and 3, then it's three.

If the only numbers are 15 and -40, it would be 5.
