Answer: d = 11/2 or 5 1/2
Step-by-step explanation:
2d - 6 = 5
+ 6 + 6
2d = 11
/2 /2
d = 11/2 or 5 1/2
Answer: 135.8
Step-by-step explanation:
the formula for this is πr²H/3
π4.4^2x6.7/3
407.5/3
135.8
1,038/12= 86.5833333 86x12=1,032
1,039-1,032=7 left over So you’ll need 87 boxes
Answer:
After finding like terms and solving, we get 
Step-by-step explanation:
We need to find like terms and simplify the expression 
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:

So, after finding like terms and solving, we get 
<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:

So, the answer will be: 
Answer:
126
Step-by-step explanation:
54 + x = 180
x = 180 - 54
x = 126
