First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to
Answer:
80,000 people would answer in a town of 200,000 people
Step-by-step explanation:
b =-4 (y-intercept)
x =0
m = 0 (the line doesn't have a slope)
y = mx + c
y = 0(0) + (-4)
y = - 4
The answer would be 92 by 92. Rectangular area only refers to the shape of the area. Squares are special types of rectangles.
368/4 equals 92.
I divided by 4 because a rectangle has four sides.
