The square of a positive integer added to 4 times the integer is 437..

x2 + 4x = 437

I chose to do this by completing the square..

x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides

x+2 = ±√441
x = -2 ± 21

x = -23 or x = 19
x = 19

A charity has received donations totaling $2370. However, this is only two-fifths of its goal
quester [9]
2370 / (2/5) = x / 1...2370 to 2/5 = x to 1
cross multiply
(2/5)(x) = (2370)(1)
2/5x = 2370
x = 2370 * 5/2
x = 11850/2 = 5925 <== their entire goal
