Answer:

p = 48

Step-by-step explanation:

If p is inversely proportional to the square of q

This is written Mathematically as:

p ∝ 1/q²

p = k × 1/q²

p = k/q²

Cross Multiply

k = pq²

k = Constant of Proportionality

Step 1

We find k

When p is 3 when q was 12

k = pq²

k = 3 × 12²

k = 432

Step 3

determine p when q is equal to 3

p = k/q²

p = 432/3²

p = 48

Answer:

Step-by-step explanation:

The figure is a parallelogram. That means the y value of g is the same as the y value of H

G( ? , b)

The x value of G is a little harder. You have to be careful what you do to c.

A is at - c which means you need to add c to get to (0,0)

In addition, you go out d units to get to F. So the x value of G = c + d

the complete answer is G(c + d,b)
