I put a link to the question within the word document.

h=24cm

Step-by-step explanation:

The diagram is shown in the attachment.

We need to use similar triangles to find the height of triangle ABE.

From the diagram, triangle DBC is similar triangle ABE.

We can find similarity ratio using AE:DC=20:10

This means the similarity ratio from triangle ABE to triangle DBC is 2:1

If the height of triangle ABE is h, then the height of triangle DBC is ½h.

The sum of the two heights is 36.

h=24cm

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
