There are 26 letters in the english alphabet, asussuming that they are all upper case, you would multiply 26×6 to find all of the different combinations of numbers.
there are 1000 possible ways to organize the nine individual numbers (000, 001, 002,...,999)
I hope that helps, I am not really sure how you would go on from there, good luck!
Answer:
<h3>
A = 0.5(2x+6)(6x+13) = 6x² + 49x + 78</h3>
Step-by-step explanation:
H = 2x+6 - the hight
3H = 3(2x+6) - triple the hight
3H-5 = 3(2x+6) - 5 - five less than triple the height
Area of triangle: A = 0.5BH
B = 3(2x+6)-5 = 6x + 18 - 5 = 6x + 13
H = 2x+6
So:
A = 0.5(2x+6)(6x+13) = (x+6)(6x+13) = 6x² + 13x + 36x + 78
A = 6x² + 49x + 78
Answer:
c cause it says length = 5x
All you have to do is divide the left side of the ratio by 5 and the right side of the ratio by 7. The one that comes out even on both sides is the correct one.
Answer:
Okay Buddy again sigh*
- Solve 1 equation for 1 variable. ( Put in y = or x = form)
- Substitute this expression into the other equation and solve for the missing variable.
- Substitute your answer into the first equation and solve.
Okay Hope it helps Buddy!
