Hello!
your answer is: 4
2 cubed is also written as: 2³
2 squared is also written as: 2²
so the re-written equation is: 2³ - 2²
To solve, simplify by doing the exponents.
2³ = 8
2² = 4
8 - 4 = 4
I hope this helps, and have a nice day!
Answer:
The proof is below.
Step-by-step explanation:
Given two triangles similar.
we have to prove that ratio 
As, △OKE∼△VDE
∴ their corresponding sides are in same proportion.
⇒ 
⇒ [tex}\frac{EK}{EO}=\frac{VE}{ED}[/tex]
Hence Proved.
Ok so a rectangular prism is the same as a rectangular cuboid.
The surface area is all the areas of the faces added together ->
There are three different faces that occur twice
length -> l
width -> w
height ->h
2( l * w ) + 2( l * h ) + ( w * h )
2 ( 10 * 4.5 ) + 2 ( 10 * 8.75 ) + 2 ( 4.5 * 8.75 ) = 343.75 cm2
Therefore it's A
Hope this helps :P
Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.
Let us use the Pythagorean theorem.
a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft
The height of the wall is 40 ft.
It is 40 40. 40 is the answer
