Be kind and me with this question make sure it's correct warning: only if your good at math

You have a square that was has a length of 2.

It underwent an operation to become two.

It was created from another square that had a side of x units long.

The relationship between the child square and the parent square is 1/2.

The side of the child is 1/2 as big as the parent [As far as I know parent and child are actual terms].

So let the Parent's side = P and let the child's side = 2 (given)

1/2 P = 2 Multiply both sides by 2

2(1/2 P] = 2*2

P = 4

The parent's side is 4 which is also the answer.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
