Tim is a wildlife biologist studying deer parasites. During a study,
he finds that 12 out of 32 deer were affected by parasites. How
many of the 1200 deer in the local population would he expect to
be affected by parasites?
a) 144
b)320
c)384
d)450

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

you would need to know all the numbers that are on there
