Find two real numbers that have a sum of 8 and a product of 13

The two numbers are 5.73 and 2,27

Step-by-step explanation:

Let the two numbers be x and y

Make x the subject in the first equation

Substitute 8 - y for x in the second equation

Open brackets

Equate to 0

Solve using quadratic formula

Where

So:

Split

or

or

or

Recall that

When

When

Hence, the two numbers are 5.73 and 2,27

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

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.
