PLEASE HELP X+11/8 = -3

Show your work in details if you can, I have a hard time understanding this.

Assume that a population of 50 individuals has the following numbers of genotypes for a gene with two alleles, b and b: bb = 30, bb = 10, and bb = 10. calculate the frequencies of the two alleles in the population’s gene pool.

Which statement is always true? a. square bcdf is a rectangle. b. rectangle gjkm is a square. c. quadrilateral stpr is a trapezoid. d. parallelogram abcd is a rhombus.

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?
