Answer:
5/2 x^2y^2
Step-by-step explanation:
( x^2 - 3/5y^2)^2 + (3/4 x^2 + 4/5 y^2)^2 - (5/4x^2 - y^2)^2
= x^4 - 6/5x^2y^2 + 9/25y^4 + 9/16x^4 + 6/5x^2y^2 + 16/25y^4 - ( 25/16x^4
- 5/2x^2y^2 + y^4)
Distributing the negative over the parentheses:-
= x^4 - 6/5x^2y^2 + 9/25y^4 + 9/16x^4 + 6/5x^2y^2 + 16/25y^4
- 25/16x^4
+ 5/2x^2y^2 - y^4
Bringing like terms together
x^4 + 9/16x^4 - 25/16x^4 - 6/5x^2y^2 + 6/5x^2y^2 + 5/2x^2y^2 + 16/25y^4 + 9/25y^4
- y^4
Adding like terms:-
= 5/2 x^2y^2 Answer
It’s an isosceles triangle, so both the legs will be congruent, and then we can use the Pythagorean thrm
8^2+8^2=x^2
64+64=x^2
128=x^2 *square root both sides*
x=11.3
So the answer would be C
In order to solve your question, you first have to understand what 1/3 of 36 is. you can do that by dividing 36/3.
when you do this you get the answer of 12. 1/3 of 36 is 12.
to get the 2/3 part. Add 12 to the existing part that you have.
Therefore, you have 24 plant eaters.
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x
Answer: 1)The drivers with low alcohol in take from the breathlyser, being above the limit, A = 5/100;
2)The drivers above the alcohol limit, give reading below that level, B = 15/100;
3) The drivers above the alcohol limit that are arrested at radom by police, C = 12/100
Step-by-step explanation: a) A + B + C = 5/100 + 15/100 + 12/100 = 32/100
b) 1 - ( A + B + C) = 1 - 32/100 = 68/100
c) A = 5/100
d) 1 - 5/100 = 95/100
