Factor out the trinomial. Find factors of x² and 6 that would, when added, give you 5x
x² = x * x
6 = 3 * 2
(x + 3)(x + 2) are your binomials.
To solve for x, set each parenthesis = 0
x + 3 = 0
x + 3 (-3) = 0 (-3)
x = -3
x + 2 = 0
x + 2 (-2) = 0 (-2)
x = -2
x = -3, -2
hope this helps
Answer:
{ 6, 9, 16, 18 }
Step-by-step explanation:
To find the range substitute the values of x from the domain into the equation for y, that is
x = - 3 : y = - 3 + 9 = 6
x = 0 : y = 0 + 9 = 9
x = 7 : y = 7 + 9 = 16
x = 9 : y = 9 + 9 = 18
The y values are the range of the relation, that is
y ∈ { 6, 9, 16, 18 }
Answer:
Earth's average distance from the Sun is 
times more than is from the Moon.
Step-by-step explanation:
Given the average distance of Earth from the Sun is 
kilometers.
Also, the approximate distance of Earth from the Moon is 
kilometers.
For this, we will divide the average distance of Earth from the Sun by approximate distance of Earth from the Moon.
So,
Answer:
328
Step-by-step explanation:
If z is 0, then x has 9 choices. Therefore, z and x can be chosen in (1 × 9) + (4 × 8) = 41 ways. For each of these ways, y can be chosen in 8 ways. Hence, the desired number is 41 × 8 = 328 numbers 3-digit even numbers exist with no repetitions.
