Answer:
3:1
Step-by-step explanation:
Take the fraction and simplify it:
12/4 = 3/1

Solution ~
or it can also be expressed as ~
Answer: We should add the constant 81 to the expression to have a perfect square trinomial.
The perfect square trinomial that would be formed would result from (x + 9)^2.
We can use foil to prove it.
(x + 9)(x + 9)
x^2 + 9x + 9x + 81
x^2 + 18x + 81
81 is the value that must go with 18x in the middle to form the perfect square trinomial.
Answer:
the statement shows the inverse property of addition as the sum of a number and its inverse is zero.
Step-by-step explanation:
As we know that Inverse Property of Addition states if you add any number to its opposite, the result will be zero.
For example, 13 + (-13) = 0 shows that -13 is the additive inverse of 13.
In other words, the sum of a number and its inverse is zero.
Now checking from the available options,





Thus,

Therefore,
the statement shows the inverse property of addition as the sum of a number and its inverse is zero.
D. 311 divided by 12 = 25.91
The nearest tenth would be 25.9
