Answer: that the variable can be any number.
Step-by-step explanation:
So we have a linear equation and we end with a relation of the way:
x = x
an example can be if we have:
2*x + 4 = 2*(x + 2)
if you solve that, you will end with a relationship x = x
this means that any value of x will made that equality true.
so x can be any number.
Answer:
20+20+6+6+30+30=112cm^2
Step-by-step explanation:
The equivalent polynomial is 12x^2 -23x - 24.
You can get this by multiplying the two parenthesis by each other.
First start by multiplying the two front numbers:
4x * 3x = 12x^2
Then multiply the outermost numbers:
4x * -8 = -32x
Then multiply the innermost numbers:
3x * 3 = 9x
Then multiply the last numbers:
3* -8 = -24
Now combine all of them to get the above polynomial.
Answer:
195.500
Step-by-step explanation:
5 percent of 170,000 is 8,500.
Since 3 years pass we're multiplying 8,500 by 3.
8,500
x 3
_____
25,500
Now we just add 170,000 + 25,500, and we get 195.500.
Hope I at least somewhat helped, and if I didn't, at least I tried.
