The given expression is

We have to find the discriminant first . And for that, first we need to move whole terms of the left side to right side, that is


The formula of discriminant is

Substituting the values of a,b and c, we will get

And since the discriminant is greater than 0, or it is positive so we have two real roots.
Therefore the correct option is B .
Answer:
B) -4
Step-by-step explanation:
(5/2)x + y = 2
x + (2/3)y = 4
y = 2 - (5/2)x
x + (2/3)(2 - (5/2)x) = 4
x + 4/3 - (5/3)x = 4
(-2/3)x = 8/3
-2x = 8
x = -4
Answer:
Each side is 15 ft
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
225 ft^2 = s^2
Take the square root of each side
sqrt ( 225 ft^2) = sqrt ( s^2)
15 ft = s
Each side is 15 ft
First, you would get the decimal form of 67% by moving the decimal (At the end of most whole numbers.) over two, giving you .67.
Next, multiply 296 by this new decimal- .67*296=198.32.
There you go! : )
