The patio is rectangular and has a total area of 24 square feet. you are building a rectangular fish and want the length of the pond to be twice the width. you also need to add a 1foot barrier around the entire pond. suppose the total area of the patio represented by the polynomial 2x^2+6x+4, where x is the width of the fish pond

i think ur answer is   (3,-1)

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

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.
