What is 7/8 expressed as a percent?

87.5%

Step-by-step explanation:

1. Convert 7/8 to a decimal -> 0.875

2. Move the decimal point two places right

3. Take away the zero and you'll get 87.5

4. put your answer in

Byeeee, get a hundred!

a = 11 : 4

b = 38

c = 1 for every 6

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
