Answer:
( x - 6 ) ( x - 3 ) (x + 4)
Step-by-step explanation:
Lets x = missing angle
x = 180 - (60+80)
x = 180 - 140
x = 40
answer
40
Answer:
7.5
Step-by-step explanation:
10x + 8x + 6x = 180°
24x = 180°
x = 180°÷24
× = 7.5
Answer ; 10x - 20
Explanation; Multiply each term in the parenthesis by 10. Then multiply the numbers, and you get your answer.
If you observe carefully, you can see that the graph is crossing x-axis at the points 1 and 9. This means x = 1 and x = 9 are the roots of the polynomials and x - 1 and x - 9 are thus the factors of the polynomial.
We can express the polynomial as the product of its factors. So the above polynomial can be expressed as (x - 1)(x - 9)
Thus, the answer to the question is option D
