Step-by-step explanation:
Greetings!
To find the average of a set of numbers, you add them together and divide by the amount of numbers.
In an expression:
Follow PEDMASS


The average of the two numbers is
26.
Hope this helps.

For the rectangle do 10x15 to get 150cm squared
14-10 is 4 so triangle height is 4
Width is 5 as given
4x5 is 20 divide by two as triangle so 10cm squared
150+10=160cm squared
the equations are already in slope-intercept form, therefore

so their slopes are 2 and 4.
parallel lines have exactly the same slope, these ones do not, so they're not parallel.
perpendicular lines, have negative reciprocal slopes, in short, their product gives -1, 2*4 ≠ -1, so they're not perpendicular either.
Answer:
8
Step-by-step explanation:
The interior angles of a triangle always add up to 180°.
As QE=ED=QD
so, ∠Q=∠E=∠D=180°/3=60°
As, ∠D=5x+20
60=5x+20
5x=40
x=8
Hope, this helps you.
