Answer:
9
Step-by-step explanation:
The factors of 18 are : 1, 2, 3, 6, 9, 18
The factors of 27 are : 1, 3, 9, 27
The common factors are : 1, 3, 9
The gcf is 9
X - hours that passed after 10 pm
(x+1) 36 = x * 42 | / 6
(x+1)6 = 7x
6x+6 = 7x |-6x
x=6
They will travel same distance at 4 am.
<span>(1.3t3 + 0.4t2 – 24t) + (8 – 18t + 0.6t2)
In adding polynomials, make sure that each term is grouped together.
1.3t</span>³ + 0.4t² - 24t
<u> + 0.6t² - 18t + 8</u>
1.3t³ + 1.0t² - 42t + 8
In a polynomial equation, arrangement of each term is dependent on the exponential number. It should be from the highest exponent to the lowest.
The distance between the point (3, 5) and a line with the equation 5x – 3y + 10 = 0 will be 10 / √(34) units.
<h3>What is the distance between a point and a line?</h3>
Let (x₁, y₁) be the point and ax + by + c = 0 be the line.
Then the distance between a point and a line will be
