Answer:
Step-by-step explanation:
The discriminant is found in
which is part of the quadratic formula. In
, a = 4, b = 10, c = -16. Filling in for the discriminant:

It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.
In
, a = -16, b = -7, c = 3. Filling in for the discriminant:

It's positive and not a perfect square so the 2 solutions are complex rational
Answer:
25 cm
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 24^2 = c^2
49 + 576 = c^2
c^2 = 625
c = 25
Answer: 25 cm
Answer:
B. 9
Step-by-step explanation:
We assume that ...
SU = ST +TU
133 = (9x-5) +(5x+12)
126 = 14x . . . . . subtract 7, collect terms
9 = x . . . . . . . . . divide by 14
Plug in 1 for n and solve, then plug in 2, and so on until you get to 3(6)-1=17
