The last net has all of the requirements. All you have to do then is count, which means the vertices from the hexagon all add up to 12. The rectangles are supposed to encircle it to make a closed object, which gives it eight faces, hexagons included.

If the product of two number is 10 and the sum is 7 ,then the longest of the two number is

irinina [24]

Answer:

5 units

Step-by-step explanation:

Step one:

Given data

Le the first number be x

and the second number be y

So

x*y= 10-----------------1

and

x+y= 7-----------------2

from eqn 1

x= 10/y

put x= 10/y in eqn 2

$10/y+y= 7\\\\10/y= 7-y$

cross multiply we have

$10=y(7-y)\\\\10=7y-y^2$

rearrange

$y^2-7y+10=0$

the factors of the quadratic expression are

-5 and -2

$y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\$

The longest side is 5 units
