Step-by-step explanation:
![6a - 4(2a + 3)\\6a - (4*2a + 4*3)\\6a - (8a + 12)\\6a - 8a - 12\\- 2a - 12\\\boxed{\bf\:2 (-a - 6)}](https://tex.z-dn.net/?f=6a%20-%204%282a%20%2B%203%29%5C%5C6a%20-%20%284%2A2a%20%2B%204%2A3%29%5C%5C6a%20-%20%288a%20%2B%2012%29%5C%5C6a%20-%208a%20-%2012%5C%5C-%202a%20-%2012%5C%5C%5Cboxed%7B%5Cbf%5C%3A2%20%28-a%20-%206%29%7D)
Steps:
- Factorise the second term as the first is already in its simplified form.
- Solve the first term and the second term by doing the required arithmetic operations.
- Take the common factor out.
- The result will be : 2 (- a - 6).

Answer:
The answer is 8 bicycles : 15 wheels
Answer:
√x³=√(x²·x)=x√x
√xy³z=√(x·y²·y·z)=y√xyz
√18x²y=√(3²·2·x²·y)=3x√2y
√32x⁴y²=√(2⁴·2·x⁴·y²)=2²x²y√2=4x²y√2
2√16x⁷y³z⁴=2√(2⁴·x⁶·x·y²·y·z⁴)=2³x³yz²√xy=8x³yz²√xy
-3√180x⁵y=-3√(3²·2²·5·x⁴·x·y)=-3(3)(2)x²√5xy=-18x²√5xy
5√108xyz²=5√(2²·3²·3·x·y·z²)=5(2)(3)z√3xy=30z√3xy
3x√xy¹⁰z⁷=3x√x·y¹⁰·z⁶·z)=3xy⁵z³√xz
x²√x³y²=x²√(x²·x·y²)=x²·x·y√x=x³y√x
Hello!
the angles in a triangle add to 180°
------------------------------------------------------------------------------------------------------
Triangle 1
115 + 35 + 25 = 175
Since it does not equal 180 it is not triangle 1
------------------------------------------------------------------------------------------------------
Triangle 2
115 + 32 + 33 = 180
Since it does equal 180 it is triangle 2
------------------------------------------------------------------------------------------------------
The answer is triangle 2
Hope this helps!
