It is the same as 13n-25 simplified

13N. if a=0, the sum of all forces is zero so the force of friction is equal and opposite to the dragging force.

There is a formula for the "difference of squares." In this case, the answer is (3m + 13n)(3m - 13n)

21 and 21 equal 42.

The only thing equal to 4.2 is 4.2.

42% = 0.42

7x = 42 or 21x = 42

it is 42 silly deeer

Use the formula (n2 + 7) - n2 = 7, expand the equation to get n2 + 7n + 7n + 49 - n2 = 7, eliminate what you can to get 14n + 49 = 7, then isolate 'n' by subtracting 49 from both sides of the equation which will now be 14n = -42, now you divide both sides of the equation by 14 to get n = -3. Since 'n' is squared, you know that the two possible combinations of numbers can be either positive or negative. Their equation will look like this; 16 - 9 = 7, or 42 - 32 = 7, or (-42) - (-32) = 7.
