Answer:

All of them

Step-by-step explanation:

x² - x - 2

(x + 1)(x - 2)

x² + x - 2x - 2

x² - x - 2

(x - 0.5)² - 2.25

x² - 2(x)(0.5) + 0.5² - 2.25

x² - x + 0.25 - 2.25

x² - x - 2

Given the calculations shown, find the dimensions of the prism.
ra1l [238]

The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

From the prism:

Perimeter P = 2(w + l)

40 = 2(w + l)

w + l = 20   (1)

Also:

Base area (B) = wl

100 = wl   (2)

from equation 1 and 2:

w = 10, l = 10

The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.

19, find the direction angle of vector v to the nearest tenth of a degree
labwork [276]
The vector v is given by:
 v = (7, 2) - (-5, 0)
 v = ((7 - (- 5)), (2-0))
 v = ((7 + 5), 2)
 v = (12, 2)
 Then, the angle is given by:
 tan (theta) = 2/12
 theta = atan (2/12)
 theta = 9.46 degrees
 Answer:
 
The direction angle of vector to the nearest tenth of a degree is:
 
theta = 9.5 degrees
