Answer: SSS
Proof:
In ΔMLQ and ΔNPQ,
MQ = NQ (given) S
Since Q is the midpoint of LP, by definition, LQ = QP (S)
LM = PN (given) S
∴ ΔMLQ ≡ ΔNPQ (SSS)
We solve the problem by means of the method of separation of variables.
We have then:
2ty '= 4y
2t (dy / dt) = 4y
t (dy / dt) = 2y
(dy / y) = 2 (dt / t)
integrating both sides:
int (dy / y) = 2int (dt / t)
Ln (y) = 2Ln (t) + c
exp (Ln (y)) = exp (2Ln (t) + c)
exp (Ln (y)) = exp (Ln (t ^ 2) + c)
exp (Ln (y)) = exp (Ln (t ^ 2)) * exp (c)
y = c * t ^ 2 ---> y (1) = - 2.
-2 = c * (1) ^ 2
c = -2
then:
y = -2 * t ^ 2
answer:
c = -2
r = 2

Answer:
Please see the attached picture for the full solution.
*From the 4th line of the 1st image, you could also expand it using
(a +b)²= a² +2ab +b² and
(a -b)²= a² -2ab +b².
When squaring a fraction, square both the denominator and numerator.
➣(a/b)²= a²/b²
