I am guessing this is an expression that needs to be simplify or factorise or both.
If the expression goes like this and I repeat :
2 1/2 x - 3/4 (2x+5) + 3/8
5x/2 - 3x/2 - 15/4 + 3/8
5x/2 - 6x/2 - 27/8
-x/2 - 27/8
-(4x + 27)/8 Answer:
Please comment me back if I got the question incorrect.
Answer:
Volume = length x width x height.
You only need to know one side to figure out the volume of a cube.
The units of measure for volume are cubic units.
Volume is in three-dimensions.
You can multiply the sides in any order.
Which side you call length, width, or height doesn't matter.
Answer:
A theme is where and when a story or poem takes place.
I hope its correct!
Answer:
Let θ = (45 - A)°.
=> 2Tanθ/ 1 + Tan²θ
=> 2Sinθ/Cosθ / 1 + Sin²θ / Cos²θ
=> 2Sinθ/Cosθ/ Cos²θ + Cos²θ / Cos²θ
=> 2Sinθ/Cosθ/ 1 / Cos²θ
=> 2SinθCos²θ/Cosθ
=> 2SinθCosθ
=> Sin2θ
But we assumed θ = (45 - A)°,
=> Sin2(45 - A)
=> Sin(90 - 2A) (∵ Sin(90 - θ) = Cosθ)
=> Cos2A
= R.H.S
Hence proved.
