The way to read math problems is to read and do little parts at a time. Don't try and understand it all at once. That's what you try and do when you are reading a novel or a persuasive essay. Do things as you would when you are trying to parse a sentence.
The numerator is determined by the language before the word divide. What does it say? Concentrate on everything after square.
sum of 7 times x plus 3. That translates into 7x + 3
Now go look at the word square. It means that you square 7x + 3
Numerator: (7x + 3)^2
Guess what? You have already eliminated B and D. So you are left with A and C.
Denominator: difference between x and 1. Difference means subtract so you have x - 1
Denominator: 4 times the difference between x and 1: 4*(x - 1)
Now put them together.
numerator / denominator
which is C.

Answer:
25.6 units
Step-by-step explanation:
From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).
First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:
where
are the coordinates of the first point
are the coordinates of the second point
- For AB:
- For BC:
- For AC:
Next, now that we have our lengths, we can add them to find the perimeter of our triangle:
We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.
