The answer would be 2n^2+3n+ 8n-1
Answer:
D
Step-by-step explanation:
Firstly, we need to know the number of total possible results. We can do this by placing the first die in horizontal band and the second die in vertical band.
The total number of results would be 36 results.
Now, to get the number of 8s
The possible sums that can give 8 is 2 and 6, 2and 5 and 3 with 4 and 4.
All are possible two times asides the 4 and 4 that could only show one time.
This means as we can have 2 and 6 we can also have 6 and 2
The total number of expected results is thus: 5/36
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
Answer:
Ummm
Step-by-step explanation:
So what do you need help with?
The expanded form of 9,540,000 is:
9,540,000 = 9000,000 + 500000 + 40000 + 000 +00 + 0
we can also write it as :
9,540,000 = 9 x 1000000 + 5 x 100000 + 4 x 10000
and using exponents as power of 10 is:
9,540,000 = 9 x 10⁶ + 5 x 10⁵ + 4 x 10⁴
