Area is square units, so the new area would be the scale factor squared:
Scale factor is 2, so the area would increase by 2^2 = 4
The answer is B.4
John Frank Stevens, William C Gorgas and George Washington Goethals 1914 (opened)The building of the 50-mile-long Panama Canal was a collosal project, joining together the Pacific and Atlantic oceans by digging away 240 million metric tons of earth through the Isthmus of Panama.

Answer:
x=4 x=-5
Step-by-step explanation:
x^2+x-20=0
Factor
What 2 numbers multiply to -20 and add to 1
-4*5 =-20 and
-4+5 =1
(x-4) (x+5) =0
Using the zero product property
x-4 =0 x+5=0
x=4 x=-5
