Answer:
2x² - 5x - 3
Step-by-step explanation:
Given
(x - 3)(2x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x + 1) - 3(2x + 1) ← distribute parenthesis
= 2x² + x - 6x - 3 ← collect like terms
= 2x² - 5x - 3
Answer:
4.71
Step-by-step explanation:
Arc length = 2*pi*r-(pi*r)/2
Arc length = 3*2*(3.14)/4 = 4.71
The expression that represents the value of sin C - cos C is s-r
From the triangle ABC, since sin B = r and cos B = s.=, hence;
- Opposite side= r
- Adjacent side = s
- Hypotenuse = 1
If m<C is the reference angle, then;
Opposite side= s
Adjacent side = r
Hypotenuse = 1
Sin C = s and cos C = r
Hence the expression that represents the value of sin C - cos C is s-r
