There are 12 students in Mr. Smith's class and 10 students in Mrs. Jacob's class.

Further explanation

Given:

Of the student in Mr. Smith's fifth grade class, $\frac{1}{3}$ were absent on Monday. Of the students in Mrs. Jacob's class, $\frac{2}{5}$ were absent on Monday.

There were 4 students absent in each class on Monday.

Question:

How many students are in each class?

The Process:

Part-1: in Mr. Smith's class

The diagram representing all students in the class is as follows:

$\boxed{\cdot} \boxed{\cdot} \boxed{\cdot}$

$\frac{1}{3}$ were absent on Monday, that is $\boxed{\cdot}$ or 1 of 3 units.

There were 4 students absent on Monday.

Let us count how many students are in Mr. Smith's class.

$\boxed{ \ 1 \ unit = 4 \ students \ }$

$\boxed{ \ 3 \ unit = \ ? \ students \ }$

$\boxed{ \ 3 \times 4 = 12 \ students \ }$

Thus, there are 12 students in Mr. Smith's class.

Part-2: in Mrs. Jacob's class

The diagram representing all students in the class is as follows:

$\boxed{\cdot} \boxed{\cdot} \boxed{\cdot} \boxed{\cdot} \boxed{\cdot}$

$\frac{2}{5}$ were absent on Monday, that is $\boxed{\cdot} \boxed{\cdot}$ or 2 of 5 units.

There were 4 students absent on Monday.

$\boxed{ \ 2 \ unit = 4 \ students \ }$

$\boxed{ \ 1 \ unit = \ ? \ students \ }$

$\boxed{ \ 4 \div 2 = 2 \ }$

Therefore, $\boxed{ \ 1 \ unit = 2 \ students \ }$

Let us count how many students are in Mrs. Jacob's class.

$\boxed{ \ 1 \ unit = 2 \ students \ }$

$\boxed{ \ 5 \ unit = \ ? \ students \ }$

$\boxed{ \ 5 \times 2 = 10 \ students \ }$

Thus, there are 10 students in Mrs. Jacob's class.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

The polynomial is a perfect square trinomial of the form a^2-2ab+b^2 9x^2 -12x+4
