Answer:
Correct
Step-by-step explanation:
the ratio is 6 chopped nuts : 8 chocolate chips
we're looking at 9:12
from 6 to 9, it must have added 3. 3 is half of 6.
from 8 to 12, it must have added 4. 4 is half of 8.
it's the same amount because he added half of the original.

Answer:
Step-by-step explanation:
(a)
For the quadratic equation of the form ,
The discriminant is given as:
Simplifying the given quadratic equation:
[(x-7)^2] - 62 = 19
∴ (x^2) - 14x + 49 = 81
∴ (x^2) - 14x - 32 = 0
Comparing with the standard form of quadratic equation:
a = 1; b = -14; c = -32
∴ Discriminant = (b^2) - 4ac = 196 + 128 = 324
Since Discriminant > 0,
The roots will be real and distinct.
(b)
This equation can be factored as:
(x - 16)(x + 2) = 0;
∴ x = 16 ; x = -2, are the two roots of the equation.
