Answer:
A = (x^2)/2
Step-by-step explanation:
Represent the length of one side of the square by s. Then, according to the Pythagorean Theorem,
x^2 = s^2 + s^2, or x^2 = 2s^2, or (solving for s^2), s^2 = (x^2)/2
This last result is the area of the square in terms of x: A = (x^2)/2
Answer:
The answer is 4.
Step-by-step explanation:
Since the fractions have the same denominators, all you have to do is subtract 1/5 from 1/5. When you subtract the numerators (1-1) you get 0. That would make the fraction 0/5, but that does not have to be included in the answer since it has no value. Subtract the whole numbers (23-19) to get 4.

216 I think because 3 times negative 2 is -6 the -6^3=6*6*6=216
Answer:
C) 6:1
Step-by-step explanation:
The second number must be a one. To do that, it would have to be multiplied by 4. That means we have to multiply the first number by 4 also:
3/2*4=6
So it’s 6:1
. The sum of angels in the triangle must be 180
Therefore
1) 180 - (40+85)= 55
2)180-(14+30)= 136
