Substitute the values of x, y and z to the expression:
The answer to this question is answer choice C.
For the SSS postulate, we need 3 pairs of congruent sides. However, in the image, there are only 2 pairs.
The missing pair in the image is AC and DF. If those are congruent, the triangle can be proven congruent by the SSS postulate.
Hope this helps! :)

x = mindy's height
2x - 20 = 66
-20 -20
2x = 46
/2 /2
x = 23
Solving the quadratic function, it is found that the particle returns to the ground after 7 seconds.
<h3>What is the quadratic function for the particle's height?</h3>
The particle's height after t seconds is modeled by the following equation:
s(t) = -16t² + v(0)t.
In which v(0) is the initial velocity of the particle, which in this problem is of 112 ft/s, hence:
s(t) = -16t² + 112t.
The particle hits the ground when s(t) = 0, hence:
s(t) = 0
-16t² + 112t = 0
-16t(t - 7) = 0.
Hence the non-trivial solution is:
t - 7 = 0 -> t = 7.
The particle returns to the ground after 7 seconds.

Step one. $5.00 - 9 peppermints
= $5.00 - $1.35
= $3.65
Step two. Figure out how many 25 cents are in $3.65.
$3.65 divided by .25
= 14.6 So David can buy 14 sour candies.
