Answer:
1.
Part A: Yes, it is (a - b)².
Part B: a² - 2ab + b² => (x - 6)² = x² - 12x + 36.
Part C: x² - 12x + 36.
2.
Part A: Not a special product.
Part B: Binomial distribution => (x + 8)(x + 1) = x² + 9x + 8.
Part C: x² + 9x + 8.
3.
Part A: Yes, it is (a + b)²
Part B: a² + 2ab + b² => (3x + 2)² = 9x² + 12x + 4.
Part C: 9x² + 12x + 4.
4.
Part A: Yes, it is (a + b)(a - b), a difference of squares.
Part B: a² - b² => 4x² - 49
Part C: 4x² - 49
5.
Part A: Not a special product.
Part B: Binomial distribution => (x - 5)(2x - 5) = 2x² - 15x + 25.
Part C: 2x² - 15x + 25
Answer:
hiiiiiiiiiiiii
Step-by-step explanation:
Basically you need to find what 15% of 136.45 is. You do this by changing the percent to a decimal, so 15% would be .15. Following this, you would multiply 136.45*.15. This will give your answer.
Answer: 
Step-by-step explanation:
Given
The volume of the spherical solid is 
It is melted to form a solid cube
Suppose the edge length of the cube is 
The volume of the sphere is 
![\Rightarrow 123,456=a^3\\\Rightarrow a^3=123,456\\\text{Factorising 123,456}\\\Rightarrow a^3=2^6\times 3\times 643\\\\\Rightarrow a=\sqrt[3]{2^6\times 3\times 643} \\\\\Rightarrow a=4\sqrt[3]{ 3\times 643}\\\\\Rightarrow a=49.79\ m](https://tex.z-dn.net/?f=%5CRightarrow%20123%2C456%3Da%5E3%5C%5C%5CRightarrow%20a%5E3%3D123%2C456%5C%5C%5Ctext%7BFactorising%20123%2C456%7D%5C%5C%5CRightarrow%20a%5E3%3D2%5E6%5Ctimes%203%5Ctimes%20643%5C%5C%5C%5C%5CRightarrow%20a%3D%5Csqrt%5B3%5D%7B2%5E6%5Ctimes%203%5Ctimes%20643%7D%20%5C%5C%5C%5C%5CRightarrow%20a%3D4%5Csqrt%5B3%5D%7B%203%5Ctimes%20643%7D%5C%5C%5C%5C%5CRightarrow%20a%3D49.79%5C%20m)
Answer:
16.3 repeating
Step-by-step explanation:
3x-4(4)=65
3x-16=65
3x=65-16
3x=49
x=49/3
x=16.3 repeating
