Answer:
Like Terms: and .
Coefficients: and .
Constant:
Step-by-step explanation:
"Like terms" are terms whose variables (and their exponents such as the in ) are the same. In other words, terms that are "like" each other.Example: , , and are like terms because they all have .
Coefficients are a number used to multiply a variable. In the above example, the coefficients would be , , and . In your problem, they're and .
Constants are numbers not attached to variables. See the diagram attached.
Let me know if there are further questions.
Step-by-step explanation:
Actually, it isn't that hard. Remember the difference of squares? (a + b)(a - b) = a² - b² and in this case 9 is a and 4x is b so our answer is 81 - 16x².

It should be 13.9, just divide 27.8 by 2
Answer:
Option (A)
Step-by-step explanation:
Let the equation of the line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Slope of the line passing through two points (0, 5) and (4, -7),
m =
=
= -3
As slope of the line is negative, Options (A) and (B) will be the possible options.
Therefore, equation of the line passing through (4, -7) will be,
y - (-7) = -3(x - 4)
y + 7 = -3(x - 4)
Therefore, Option (A) will be the correct option.
