Answer:
Sam is correct since he followed the rule of powers.
Reina is incorrect.
Step-by-step explanation:
Rule of a power raised to a power.
To raise a power to a power, multiply the powers.
Sam is correct since he multiplied the exponents correctly.
if the value of the denominator is 0
the fraction becomes "undefined"
so, any value of "x" that makes it 0
is not a valid value for "x", and thus
not part of the domain
let's set the denominator to 0, and find out which one(s) are those if any
Answer:
b Square
Step-by-step explanation:
I literally just counted
So your total is $6584
tution costs $704 more than room and board
you know nothing about how much the room and board cost so thats your "naked variable" so chose a variable to go in place of that. im going to coose r.
tuition($704 more than room and board): r +704
room and board(you know nothing about it): r
so add it all together you get r+704+r=your total.
sole the equation
2r +704= 6584
-704 on both sides
you get 5880 so it would come to 2r= 5880
divide by 2 on both sides
so r= 2940
r is the room and board so put 2940 in place of r in the equation you get from your variables which are r and r+704
so the final equation is 2940 +704 and your final answer is 3644
