Answer:
I know you could easily solve this just looking at it.
But if you want the algebraic solution:
x + x^2 = 30
x^2 + x -30 = 0
a = 1
b = 1
c = -30
Using the quadratic formula:
x = [ -b +- sqr root (b^2 - 4ac) ] / 2a
x = [-1 +- sqr root (1 - 4 * 1 -30) ] / 2*1
x = [-1 +- sqr root (1 + 120) ] / 2
x = -1 +- sqr root (121) / 2
x1 = (-1 + 11) / 2 = 10 / 2 = 5
x2 = (-1 -11) / 2 = -12 / 2 = -6
Answers are 5 and -6
5 + 5^2 = 30
-6 + (-6)^2 = 30
-6 +36 = 30

Answer:
12
Step-by-step explanation:
Compare and contrast the European views and the Native American views on property.
38/?=19 ?=2
36/2=18
area of rectangle = length x width
so 19x18 = 342
