On saturday leo and his brother drove into town to visit their mom leo is trying to remember how much he spent on gas and tolls tolls were a dollar $1.75 each and he also spent $28 at the gas station to fill up what are the terms and their factors and coefficients of the algebraic expression that represents the total cost of gas and tolls

total amount spent on toll=$1.75 each(two in number i.e at two tolls)

                                              =1.75×2=$3.50

amount spent on gas station for filling up the gas =$ 28

suppose amount spent on two tolls and amount spent on gas station for filling the gas are two solution of an algebraic expression.

now , writing in terms of algebraic expression

⇒(x-3.50)(x-28)

⇒(x-7/2)(x-28)

⇒x(x-28)-7/2(x-28)

⇒x²-28 x-7/2 x-

⇒x²- +98

terms are, x²,-,98

coefficient of x²=1

coefficient of x= =-1/2×7×3×3×x

constant term=98=7×7×2

coefficients of the algebraic expression that represents the total cost of gas and tolls=-[coefficient of x]=63/2=28 [amount spent on gas] +3.50 [amount spent on toll]=$31.50

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.  

one set of data has more variation than the other. hope this !
