Answer:
The equivalent expression is 
Step-by-step explanation:
The distributive property says for any numbers <em>a, b c</em>, and <em>d</em>

which basically says you should multiply the coefficient
by every term in the parenthesis to get an equivalent expression.
Applying the distributive proper to the expression
we get:


which is an equivalent expression to
.
Each time they assume the sum is rational; however, upon rearranging the terms of their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.

Answer:
D
Step-by-step explanation:
I believe D is the answer because 10^-3 = 0.001 ; there is only one answer that has 0.001 in the correct exponential form (10^-3).
Also, for the future, to correctly figure out what the exponential form, try to take the number given, let's say 10^-2 (^ means to the power of), and move the decimal place to the left, two decimal places (because of the power of -2).
Ex: 10.0 --> 0.01

Answer:
2m+2m
Step-by-step explanation:
Answer:
2.5+7.5+-10n+-20
Step-by-step explanation:
Multiply everything on the inside by the number on the outside and put it together with addition signs.
-2.5(-3+4n+8)
-2.5*-3=7.5
-2.5(7.5+4n+8)
-2.5*4= -10
-2.5(7.5+-10n+8)
-2.5*8=-20
-2.5+7.5+-10n+-20
