Given 7 spaces, each space can consist of a letter (26 letters in the alphabet), a number (numbers 0 to 9: for a total of 10 numbers), and a space (1).
Adding the amount of letters, numbers, and a space equals:
26 + 10 + 1 = 37 possible characters for each space on the license plate.
Since repeat characters are allowed, each space can have 37 possible characters.
The plate has 7 spaces so:
37 x 37 x 37 x 37 x 37 x 37 x 37
= 37^7 different combinations.
Answer:
18
Step-by-step explanation:
To find this we must divide 45 by 20 which gives the answer of 2.25. As we know this we now must multiply that by 8 resulting in to 18.
Therefore the answer is 18
Answer:
x = 4
Step-by-step explanation:
Given
(x - 7) = - 2
Multiply both sides by 3 to clear the fraction
2(x - 7) = - 6 ← distribute left side
2x - 14 = - 6 ( add 14 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
2 solutions. This is because the parabola will cross the x axis twice. We know this because -5 means the vertex will be 5 units below the x axis. and the parabola opens upwards because the first coefficient is positive. Hope this helped :)
