B+c is 16
16 + 25 Is 41
I don't know d sorry
B. 19.8
Use the Pythagorean theorem:
14.2^ + x^ = 24.4^
201.64 + x^ = 595.36
x^ = 393.72
x = 19.84
-6 so option D is the answer
Answer: x = (-3,3), y = (-5,5)
Step-by-step explanation:
Add both of the equations together, for 
. Now we can divide both sides by 3, getting
. we subtract the first equation from our equation we just got, getting 
y= (5,-5). once we plug that in, we get 
, 
x = (-3,3)
Explanation:
Volume of rectangular prism: Length * Width * Height
Solve:
<u></u>
<u>1)</u>
Volume: 9 * 9 * 9 = 9³ = 729 cm³
<u>2)</u>
Volume: 7 * 3 * 2 = 42 m³
<u>3)</u>
Volume: 7 * 7 * 7 = 7³ = 343 cm³
