Answer:
d = 3
Step 1: Simplify both sides of the equation.
Step 2: Flip the equation.
Step 3: Add 1/2 to both sides.
36%=36/100=9/25
36% of 125=9/25*125=45 :)
The formula for a discriminant is b^2-4ac
so, (-7)^2 -4(3)(6) simplifies to 49-72 which equals -23
Answer:
option a
step-by-step explanation:
To rationalize the expresion we need to multiply and divide the expression by the conjugate of the denominator as follows
sqrt(9) / (sqrt(3) + sqrt(x)) = sqrt(9) ((sqrt(3) - sqrt(x)) / ((sqrt(3) + sqrt(x))(sqrt(3) - sqrt(x)))
3((sqrt(3) - sqrt(x)) / (3 - x)
So the result es option a:
(3sqrt(3) - 3sqrt(x)) / (3 - x)
