Answer:

Option D

Step-by-step explanation:

Whenever we take a square root of a number the ± sign is with it like here in the question

$x^2=20\\\\Apply\ square\ root\ on\ both\ sides\\sqrt{x^2}=\sqrt{20} \\\\The\ square\ cancels\ out\ with\ the\ root\x=\sqrt{20}$

And then x = ±4.47 which means x has two values one is +4.47 and the other is -4.47 so Option D is our answer.

Answer:

19.4in

Step-by-step explanation:

1) formula for area of a triangle:

(b*h)/2=a

the area and height are already given so lets substitute them in the formula.

(b*23.8)/2=230.86

1) multiply by 2 on both sides

b*23.8=461.72

divide by 23.8 on both sides

b=19.4

the base is 19.4 in

hope this helps
