Answer:
x = 2
Step-by-step explanation:
f(x) = x + 8
f(x) = 10
10 = x + 8
minus 8 from the both sides
10 - 8 = x
2 = x
x = 2

Answer:
height of the tree is 30 feet
Step-by-step explanation:
a tree casts a shadow 42 feet long . at the same time, a person 5 feet tall casts a shadow 7 feet long.
shadow of a 5 feet tall person is 7 feet long
Let x be the height of the tree
shadow of a 42 feet tree is x feet long
Make a proportion
cross multiply
divide by 7 on both sides
x=30
So height of the tree is 30 feet
Bottom Side Surface Area:
(24 inches + 24 inches + 24 inches) * (30 inches)
= 72 inches * 30 inches
= 2160 inches squared
--------
Top Side Surface Area:
24 inches * 30 inches
= 720 inches squared
--------
Length of the diagonal (D) which needs to be measured:
*Use Pythaogras's theorem...
24^2 + 10^2 = D^2
D=√(24^2+10^2)
D=26 inches
------------
Measure the surface area of the two ramps:
26 inches * 30 inches * 2
= 1560 inches squared
-----------
Total surface area:
2160 inches squared + 720 inches squared + 1560 inches squared
= 4440 inches squared
---------
Answer:
4440 square inches
