Answer:
1) They were multiplied by one power of ten because 2.5x 1^10 is 25, and so that it is easier to divide.
19.625/ 2.5 * 10/10 = 196.25/25
Hope this helps plz hit the crown ;D
There is no value that x cannot be for linear equations.
Thus, the domain is ALL REAL NUMBERS.
CHOICE B.
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Combine like terms
Divide by 
both sides
therefore
<u>the answer is</u>
the value of p in the linear equation is 
N = ((n-1) + 4) + 4, to my understanding.
although your answers seem right written in the columns, but your method of applying numbers to equation seems incorrect in 'expand' column. for example, answer for 3 should be something like this...
3 21 17+4
4 25 21+4
hope it helps.
