This is the function

{2x}^{2}  - 2 {x}^{1}  + 12

Then factor 2 out

2(x^2- x + 6) = 0

Divide both side by two and use the quadratic formula to get the following

(x - 3)(x + 2) = 0

X=3 And x=-2 and don't forget to Chek them

Use the Pythagorean Theorem to find l. 1 l l = 7 [?] ft 13 ft 1 2 ft a C с Pythagorean Theorem: a2 + b2 = c2 b Enter​
IgorC [24]

Answer:

l = √10 ft

Step-by-step explanation:

Using Pythagorean Theorem, a² + b² = c², where,

a = ½(2) = 1 ft

b = 3 ft

c = l

Plug in the values

1² + 3² = l²

1 + 9 = l²

10 = l²

√10 = l

l = √10 ft

Draw a line segment and copy it to the right of the original segment and explain your steps and justify each step used.
ozzi
I think this is how you do it: A line of segment is a line with a circular round ball at each end of the line. The line can be straight or diagnal. You draw that, and then draw a line like that right next to the line that you just drew. Then you explain how you did that/ your steps.
