(4w + 3) - (2w + 1)

It's not a fraction.. I keep getting answers that are fractions..

2w + 2

Step-by-step explanation:

(4w + 3) – (2w + 1) = 4w + 3 – 2w – 1 = 2w + 2

Step-by-step explanation:

(4w + 3) - (2w + 1) = 4w + 3 - 2w - 1

                            = 2w + 2

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

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
