Multiply. (w-7) (w+4)

Mathematics

Use the FOIL (first, outside, inside, last) to expand the terms in the brackets.

(w - 7)(w + 4)

first: w × w = w²

outside: w × 4 = 4w

inside: -7 × w = -7w

last: -7 × 4 = -28

Now you add all the terms together to get:

w² + 4w - 7w - 28

This simplifies to give you:

w² - 3w - 28

Hope that helps! :)

Anna71 [15]

Answer:

B. Line B

General Formulas and Concepts:

<u>Algebra I</u>

Undefined slopes are when x equals a certain number.

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

From the given choices, B is the correct answer.

A has a slope of 0, so <em>m</em> = 0 and would become a horizontal line.

C has a negative slope, so it is not undefined.

D has a positive slope, so it is not undefined.

B shows a vertical line, and so it has an undefined slope.
