[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]

Step-by-step explanation:

1) Use difference of squares: a² - b² = (a + b) (a - b).

[tex]( {x}^{2} - {3}^{2} )(3x + 2)[/tex]

2) Simplify 3² to 9.

[tex]( {x}^{2} - 9)(3x + 2)[/tex]

3) Use The FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]

Therefor, the answer is 3x³ + 2x² + -26x -18.

calculate the length of the semicircle to 1 decimal place.
50 m

Answers

Answer:

157.1 m

Step-by-step explanation:

Here, we want to calculate the length of the semi-circle

This simply refers to the circumference of the semi-circle

Mathematically, the circumference is half that of a full circle

The circumference of a full circle is;

C = pi * d

For half circle or semi-circle;

It is ;

C = (pi * d)/2

D = 50 m

The circumference is thus;

C = 50 * 3.142

C = 157.1 m
