Morgan has completed the mathematical statements shown below. Which statements are true regarding these formulas? Select three options. A = pi times r squared and C = 2 times pi times r. A = pi times r times r and C = pi times r times 2. A = (pi times r) times r and C = (pi times ) times 2. The numerical values of the area and circumference are equal when r = 2. The numerical value of the area is less than the numerical value of the circumference when r less-than 2. The numerical value of the area is greater than the numerical value of the circumference when r less-than 2. The numerical value of the area is less than the numerical value of the circumference when r greater-than 2. The numerical value of the area is greater than the numerical value of the circumference when r greater-than 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

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.

answer is

b.
