For the first one, we will have to factor out the numbers. So 2 times 4x is 8x and 2 times 5 is 10. Our new expression will now be 8x + 10 = 8x + 10. Now, since these are equal, x must equal 1.
Answer: We want to find the acceleration needed to achieve a force of 25 Newtons.
The acceleration is:
a = 25N/m
By Newton's second law, we know that:
F = m*a
Force equals mass times acceleration.
So if we want to have a force of 25N, we replace F by 25N, so we get:
25N = m*a
Solving this for the acceleration, we get:
25N/m = a
Notice that we can't get the exact acceleration as we do not know the mass of the object, but we got a general formula where we can replace the mass of the object to get the exact acceleration.
