Answer: Blake still has to mow 17,424 acres.
There are 43,560 square feet in an acre.
Blake has already mowed 60% of the lawn, leaving him 40% more to mow.
All we have to do is multiply 17,424 by 0.4 to find the number of square feet remaining.
43560 x 0.4 = 17424

Answer:
since 3x^2-7x+4=0 is in the form ax^2+bx+c=0, a=3, b=-7, c=4
Height/width=5/19
5/19=2/x
(5)(x)=(19)(2)
5x=38
5/5x=38/5
x=38/5in or 7.6in
