A paper hat is folded into the shape of a kite, as shown. A kite is shown. The left and right angles are right angles. The sides above the right angles are (3 x + 5) inches and (5 x + 1) inches. The sides below the right angle are (2 x + 1) inches and 5 inches. What total length of ribbon is needed to line the two long sides of the hat? 10 in. 11 in. 20 in. 22 in.

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

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
