Tessa solves the equation below by first squaring both sides of the equation. \sqrt{x^2-3x-6}=x-1 x 2 −3x−6 =x−1square root of, x, squared, minus, 3, x, minus, 6, end square root, equals, x, minus, 1 What extraneous solution does Tessa obtain?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

hi there!

the answer will be d: 2

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
