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.
The appropriate choice is ...
D. No. Logan should find a square with a perimeter of 64, not an area equal to 64.
Answer:
y=-3/8.0-9 y=1/3 y intercept and for the x intercept is zero
Step-by-step explanation:
6 buses with 32 students per bus.....6 x 32 = 192 students
each row seats 8 students...192/8 = 24 rows will be needed for all students
12 ÷ 3= 4. Hope this helps. ;)
