5(x² - 16)

5x² - 80

c. 5x² - 20x + 20x - 80

5x² - 80

d. 5x² - 11

D doesn't belong because 5x² - 11 is not the answer to A, B, or C.

What is the total area of the surfaces of both tables?
Anastasy [175]
There are two equal tables.
We need to add bases and multiply that by the height divided by two.
7+3=10•1=10
Now multiply that by two since there are two tables.
10•2=20

So, the tables area are 20 feet squared.

Find the equation in slope-intercept form that describes a line through (–1, 1) and (2, 3)
Butoxors [25]

Answer:

  y = 2/3x + 5/3

Step-by-step explanation:

The slope of the line is ...

  slope = (change in y)/(change in x) = (3-1)/(2-(-1)) = 2/3

Then the point-slope form of the desired line can be written ...

  y = m(x -h) +k . . . . . slope m through point (h, k)

  y = 2/3(x +1) +1 . . . . slope 2/3 through point (-1, 1)

  y = 2/3x + 5/3 . . . . . . simplify to slope-intercept form
