2 - 12 + 18
= -10 + 18
= 8
The answer is D.
Well the equation is (A^2)+(B^2)=(C^2)
A= x
B= 2x
C will always be the longest side because it is the Hypotenuse = 25
So if you plug in those numbers into the equation...
(x^2) + (2x^2) = (25^2)
x^2 + 4x^2 = 625
Combine like terms
5x^2 = 625
Divide by five to both sides
x^2 = 125
Then Square root,
x = sqrt(125)
x = sqrt(25* 5)
x = 5sqrt(5)
44 that is probably the answer since it's half
Answer:
The probability that the card is an ace is 
Step-by-step explanation:
Total number of playing cards = 52
Total number of ace cards = 4
She selects one card at random from the deck.
We are supposed to find the probability that the card is an ace
So, Probability of getting card= 
Probability of getting card= 
Hence the probability that the card is an ace is
