Face diagonal of a cube:
Step-by-step explanation:
f2 = a2 + a. Then f2 = 2a.
The answer is B.
If you look for where the two graphs intersect, you'll see that the x values of the ordered pairs are -4 (for the intersection in quadrant 2) and roughly 2.5 (for the intersection in quadrant 4). This problem is just asking you to look for those values.

Answer:
B, D, E, A, C
Step-by-step explanation:
The main idea here is to use your English comprehension skill to determine the meaning of the phrase, then use your math understanding to write it in symbols. Turning off your brain at the sight of a "word problem" will not be productive.
The wording "some number" or "a variable" or "unknown value" all refer to a variable, typically represented by a single letter. Letters commonly use are {a, b, c, x, y, z}, but variables are not restricted to that set (nor to single letters, nor lower case letters).
In most cases, the math expression is a direct translation of the English expression using the usual math symbols. Values are generally increased by addition, decreased by subtraction, squared using an exponent of 2. A product is the result of multiplication, and a quotient is the result of division.
Top-to-bottom, the boxes on the left will be filled with B, D, E, A, C.
