We need to first find the diagonal that moves along the base.
a²+b²=c²
12²+8²=c²
c²=208
c=√208
Now we have find the length for the answer.
(√208)²+14²=c²
c²=208+196
c²=404
c= 20.10 cm approx.
answer: C
3(x + 8) = 17....distribute the 3 thru the parenthesis
3x + 24 = 17...subtract 24 from both sides
3x = 17 - 24
3x = -7...divide both sides by 3
x = -7/3 or -2 1/3 <===

You will find the area of the 5 surfaces made of glass. There is a front, back, 2 sides, and the bottom. Each face is in the shape of a rectangle, so you will multiply the length by the width.
1. Front- 24 x 27 =648
Back-24 x 27 = 648
2. Side- 21 x 27 =567
Side - 21 x 27 = 567
3. Bottom - 21 x 24 = 504
Add all these together for your total amount of glass needed. The answer is 2934 square cm of glass.
178-(-395)
A positive subtracted by a negative is always positive.
178+395
=573
