Answer: 112
Step-by-step explanation:
Following PEMDAS, we need to add the numbers in the parenthesis first
8(7+7) becomes 8(14)
Now we just multiply 8 and 14
8(14) = 112
Answer:
<em>114.8</em>
Step-by-step explanation:
When you divide 75% and 2.8 you get 0.2678
When you divide 56 and 2.8 you get 20
When you divide 114.8 and 2.8 you get 41
So the greatest number divided by 2.8 is <em>114.8</em>
Answer:
[Vertex form]
Step-by-step explanation:
Given function:
We need to find the vertex form which is.,
where represents the co-ordinates of vertex.
We apply completing square method to do so.
We have
First of all we make sure that the leading co-efficient is =1.
In order to make the leading co-efficient is =1, we multiply each term with -3.
Isolating and terms on one side.
Subtracting both sides by 15.
In order to make the right side a perfect square trinomial, we will take half of the co-efficient of term, square it and add it both sides side.
square of half of the co-efficient of term =
Adding 36 to both sides.
Since is a perfect square of , so, we can write as:
Subtracting 21 to both sides:
Dividing both sides by -3.
[Vertex form]
