There are 25 children in the class 3/5 of the children in the class are boys. how many girls are their? PLZZZ

10 girls

Step-by-step explanation:

If 3/5 of the class consists of boys, (5/5 - 3/5 = 2/5) : 2/5 are girls

3/5 x 25 = 15

2/5 (girls) = 25 - 15

Therefore, 10 girls in total

your answer is the frist one

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
