Tom and jerry can spend each day making dishes and building fences. if tom spends all day making dishes, he can make 16 dishes. if, instead, he devotes his day to building fences, tom can build 4 fences. if jerry spends his day making dishes, he can make 14 dishes; if he spends his day building fences, he can build 7 fences. the opportunity cost of one fence is for tom and for jerry. therefore tom should specialize in

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
