Answer:
x = 8
Step-by-step explanation:
In an isosceles right triangle, the side length ratios are ...
1 : 1 : √2 = x : x : 8√2
The latter ratios will match the first ratios when x=8.
__
That is, x = (8√2)/(√2) = 8.
Answer:
478 people
Step-by-step explanation:
All you need to do for this problem is simply multiply 239 by 2. If the first 6 rows are 239 people, and so are the next 6, that's all you need to do.
239*2=478
Answer:
Step-by-step explanation:
The factored form of a quadratic function is f (x) = a (x - p) (x - q) where p and q are the zeros of f (x).
For eliminating you need to have a variable that cancels the other out and in this case 2x and -2x do. Then you want to take -3y+9y and add the numbers after the equal sign. -9+3
6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
