Answer:
10
Step-by-step explanation:
Rationalize the denominator by multiplying both the top and bottom by sqrt(5). you have sqrt(500) * sqrt(5) / sqrt(5)^2
simplifying we have 50/5 = 10
it would have to be a, because using pythagorean theorem, we can find that a squared + b squared = c squared. substitute that for 1 + b squared = 4; b squared=3 b = square root of 3
The answer would be -20 because you add and subtract your numbers to get 20
Answer:
a -2b
Step-by-step explanation:
2(a+2b)-a-2b
Distribute
2a+4b -a-2b
Combine like terms
a -2b
Answer:
f = -11.25
Step-by-step explanation:
-9f = 90 - f
-8f = 90
f = 90 / -8
f = -11.25
