Answer:

c² - 14cd + 49d²

Step-by-step explanation:

Given

(c - 7d)²

= (c - 7d)(c - 7d)

Each term in the second factor is multiplied by each term in the first factor, that is

c(c - 7d) - 7d(c - 7d) ← distribute both parenthesis

= c² - 7cd - 7cd + 49d² ← collect like terms

= c² - 14cd + 49d²

For the function f(x) = -4x - 5, what are the outputs for the inputs -4, 1, 3, and 11?
Anika [276]

We have to find the output values for the given input values of the function given as,

  • f(x) = -4x - 5

Here, x = Input value of the function

And f(x) = Output values

By substituting the input values of x as,

For x = -4,

f(-4) = -4(-4) - 5

      = 16 - 5

      = 11

For x = 1,

f(1) = -4(1) - 5

    = -4 - 5

    = -9

For x = 3,

f(4) = -4(3) - 5

     = -17

For x = 11,

f(11) = -4(11) - 5

     = -44 - 5

     = -49

       Therefore, Option (A) will represent the output values for the given input values.
