Question

I need major help please

Answer 1

Answer:

b

Step-by-step explanation:

It is asking for the value of the green box.

The distance formula is given too.

Q = (0,-a)

P = (b, -c)

d = √(b - 0)² + (-c - (-a))²

d = √b² + (-c + a)²

Answer 2

Answer:

$\huge\boxed{d=\sqrt{b^2+(-c+a)^2}}$$\huge\to\boxed{b}$

Step-by-step explanation:

$Q(x_1,\ y_1);\ P(x_2,\ y_2)\\\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\Q(0,\ -a),\ P(b,\ -c)\\\\\text{Substitute:}\\\\d=\sqrt{(b-0)^2+(-c-(-a))^2}=\sqrt{b^2+(-c+a)^2$
