C(a,b), because the x-coordinate( first coordinate) is a (seeing as it is situated directly above point B, which also has an x-coordinate of a) and the y-coordinate ( second coordinate) is b (seeing as it is situated on the same horizontal level as point D, which also has a y-coordinate of b)
the length of AC can be calculated with the theorem of Pythagoras:
length AB = a - 0 = a
length BC = b - 0 = b
seeing as the length of AC is the longest, it can be calculated by the following formula:
It is called "Pythagoras' Theorem" and can be written in one short equation:
a^2 + b^2 = c^2 (^ means to the power of by the way)
in this case, A and B are lengths AB and BC, so lenght AC can be calculated as the following:
a^2 + b^2 = (length AC)^2
length AC = √(a^2 + b^2)
Extra information: Seeing as the shape of the drawn lines is a rectangle, lines AC and BD have to be the same length, so BD is also √(a^2 + b^2). But that is also stated in the assignment!
Answer:
The answer would be "j"
Step-by-step explanation:
First, you would want to find the value of the original equation:
5(y + 2) + 4
Use order of operations and distribute the five.
5y + 10 + 4
5y +14
This is the value of the original equation
Now we can work through the other options, but because we already know the answer, lets see about that one.
5 x y + 5 x 2 + 4
Again, use order of operations.
Multiply first
5y + 10 + 4
and complete the equation
5y + 14, which equals our original equation.
