Answer:

Bird house is 20 ft. high.

Step-by-step explanation:

Let the height of the bird house is h feet high casts a shadow of 14 ft long.

My friend is 5 feet high and casts a shadow of 3.5 feet.

Now we see both the triangles Δ ABC and Δ XYZ are similar.

By the similar triangles theorem sides opposite to the corresponding angles will be in the same ratio.

\frac{5}{h}=\frac{3.5}{14} (from similar triangles ABC and XYZ)

h=\frac{14\times5}{3.5}=\frac{70}{3.5}=20 ft.

Therefore bird's house is 20 feet high.

Y=8x+2 (3, ), ( ,0), ( ,-6)
Kipish [7]
So basically all your doing is substituting the given number to the equation:

(3, ) (,0)
y=8(3)+2. 0=8x+2
y=24+2. 8x=0-2
y=26. 8x= 2
divide both side by 8
x=4
