Answer:
234 feet cubed
Step-by-step explanation:
6 1/2 * 8 = 52
52 * 4 1/2 = 234
Yeah put 6 on the 5-223 because it is -6 5 don’t answer
I hope this helps and gives you the right answer.
Use Pythagoras’ theorem:
a^2+b^2=c^2
But we rearrange this formula to make it
c^2-a^2=b^2
So 25^2-15^2=b^2
625-225= b^2 = 400
You now need to find the square root of 400 to find the square root of b
sqrt of 400 is 20
So 20 is the missing length in this triangle
QR = LN, so
-2x = -3y + 3
OP = VW, so
-6x =-6y + 18
(-2x = -3y + 3)*(-2) ------> 4x = 6y - 6
-6x = - 6y + 18
4x = 6y - 6
<u>-6x = - 6y + 18</u>
-2x = 12
x= - 6
