Answer:
5x+4
Step-by-step explanation:
6x+8-x-4
5x+4
The polynomial as per the given of the problem is f(x)=3x²-21x+30
Find the roots of this polynomial:
x₁=[-b+√b²-4ac)]/2a and x₂ =[-b-√b²-4ac)]/2a
Plug in : x₁ = [21+√(21²-4(3)(30)]/6 = [21+√81}/6 ; x₁ = 5
and x₂ = [21-√(21²-4(3)(30)]/6 = [21-√81]/6 ; x₂ = 2
Remark: I don't understand where did you bring √5 , it should be 5
Answer:
Point A.
Step-by-step explanation:
We know that the temperature dropped 15 degrees, and that it was initially of 5°C. So, by midnight, the temperature will be of -10°C (5-15=-10).
We also know that the distance between points is of 5°C. So, the point that we have to mark is point A, which represents -10°C.

Answer:</h3>
- 3,8 kg
- 750 g
- 7,47 g
<h3>
Step-by-step explanation:</h3><h3>3800 g => kg</h3>
(3800 ÷ 1000) kg
= 3,8 kg
<h3>
¾ kg => g</h3>
(3 ÷ 4)kg × 1000
= 0.75 × 1000
= 750 g
<h3>7470 g => kg</h3>
(7470 ÷ 1000) kg
= 7,47 kg
