Given:
A right triangle on a coordinate plane.
To find:
The area of a triangle.
Solution:
We know that, the area of a triangle is
![A=\dfrac{1}{2}\times Base \times Height](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20Base%20%5Ctimes%20Height)
From the given figure it is clear that the base of the triangle is 4 units and the height is 3 units. So, the area of the given triangle is
![A=\dfrac{1}{2}\times 4 \times 3](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%204%20%5Ctimes%203)
![A=\dfrac{12}{2}](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B12%7D%7B2%7D)
![A=6](https://tex.z-dn.net/?f=A%3D6)
The area of the given triangle is 6 units². Therefore, the correct option is B.

Answer:
Step-by-step explanation:
To solve this system of equations, let's first find the value <em>y</em>. We can replace the x in the second equation with 11 + y, since we are told in the <em>first</em> equation that x is equal to 11 + y. So, let's replace x:
2(11 + y) + y = 19
22 + 2y + y = 19
22 + 3y = 19
3y = -3
y = -1
And look at that - we've found our y-value! Now, we can replace the y in the <em>first</em> equation with -1 to find the value of x.
x = 11 + (-1)
x = 10
So, the solution to this system of equations is (10, -1). Hopefully that's helpful!
Answer:
16
Step-by-step explanation:
:)
I’m gonna say it’s 168 because:
First u just do it as if the block has nothing missing so 10•8•3=240 and then u find the volume for the missing space which is 4•3•6=72
240-72=168 <= I think is the answer
