Answer:
<em>BC = 27</em>
Step-by-step explanation:
The point B is the midpoint of AC
=> AB = BC
=> 4x - 5 = 11 + 2x
Let's calculate x to work out BC
Transferring the components containing x to the left side, and other components to the right side:
=> 4x - 2x = 11 + 5
Simplifying both sides:
=> 2x = 16
=> x = 8
Working out BC:
=> BC = 11 + 2x = 11 + 2(8) = 11 + 16 = 27
Hope this helps!
The answer is B.
This is because since f + e = c,
then a² + b² = c(f + e)
a² + b² = c(c)
a² + b² = c²
This is the correct answer
The first one is A and the second one is A
Step-by-step explanation:
The area of a triangle is 1/2×width×length. Volume of a triangular prism is 1/2×width×length×height.
Fill in and we get 1/2×10×length×4=140. length=(140×2)/(10×4)=280/40=7. So you're right.
