39x3=30x3+9x3
117=90+27
117=117
39x3=30+9x3
117=30+27
117=57
39x3=300x3+9x3
117=900+27
117=927
39x3=30x3+9
117=90+9
117=99
So the first one is correct.

Answer:
x = y = 22
Step-by-step explanation:
It would help to know your math course. Do you know any calculus? I'll assume not.
Equations
x + y = 44
Max = xy
Solution
y = 44 - x
Max = x (44 - x) Remove the brackets
Max = 44x - x^2 Use the distributive property to take out - 1 on the right.
Max = - (x^2 - 44x ) Complete the square inside the brackets.
Max = - (x^2 - 44x + (44/2)^2 ) + (44 / 2)^2 . You have to understand this step. What you have done is taken 1/2 the x term and squared it. You are trying to complete the square. You must compensate by adding that amount on the end of the equation. You add because of that minus sign outside the brackets. The number inside will be minus when the brackets are removed.
Max = -(x - 22)^2 + 484
The maximum occurs when x = 22. That's because - (x - 22) becomes 0.
If it is not zero it will be minus and that will subtract from 484
x + y = 44
xy = 484
When you solve this, you find that x = y = 22 If you need more detail, let me know.
Answer:
A translation of 3 units to the right and a translation of one unit upwards.
Step-by-step explanation:
When we analyze translations of whole figures, all the points in the figure suffer the same translation, then we only need to analyze the translation of one of the points.
This means that we can only see the translation from A to A'
First, let's find the coordinates of each point:
A (2, 3)
A' (5, 4)
The translation is given if we calculate the difference between these coordinates:
A' - A = (5, 4) - (2, 3) = (5 - 2, 4 - 3) = (3, 1)
The change in the x-value is 3.
The change in the y-value is 1.
Then we can conclude that:
A' is 3 units at the right of A
A' is 1 unit above A.
Then the translation is:
A translation of 3 units to the right and a translation of one unit upwards.
That literally makes no sense huh
