Question

I need major help please

Answer 1

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

Explanation:

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

Answer 2

b

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
