Describe a situation that can be represented by the integer 12

Total number of pens you have when you are given 9 pens when you already have 3 pens.

Step-by-step explanation:

Integers are whole numbers (0,1,2,3,4 so on )and their negative terms

like (-1,-2,-3,-4so on).

Numbers are used to quantify situation of real world so that their analysis and understanding becomes easier for humans.

we know that number of months in a year is 12

Number of months in a year can be represented by 12.

Situation 2

If you have 3 pens and is given 9 more pens.

Then total numbers of pen will be (9+2) = 12\

Thus, other situation is total number of pens you have when you are given 9 pens when you already have 3 pens.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
