The volume of a triangular prism is V = 1/2lwh. So, in order to find x, plug in the values you know and solve:
576 =  \frac{1}{2}*8*8*x
1152 = 64x
x = 18

The formula for the volume of this shape is: length * width * height/2

Knowing this, we can set up this equation:

576= \frac{8*8*x}{2}

Now, we can solve for x.  I will start by multiplying the 8s and then divide both sides by two.

1152=64x

Next, we divide both sides by 64 to find x.

x = 18

So, x is equal to 18 cm.

Elis [28]

Answer: 7

Step-by-step explanation:

8x +5 = 61

subtract 5 from both sides

8x = 56 divide both sides by 8 to get x by itself

x= 7

WILL GIVE BRAINLIEST
Olegator [25]
The answer is A.
We can first eliminate D since it uses these (<, >) signs and the lines are shaded, indicating the points on those lines are solutions.
We can also eliminate C because the y intercept in C’s lines is 2, while in the graph, they are both 3.
Finally, we can look at both inequalities on the graph and see that the shaded areas are both underneath the line. This means that y is less than the equation for the line, eliminating B
So, the answer is A
Hope this made sense!!

What is the least common multiple of 4 and 12? O 4 O 12 O 24 o ) 48​
densk [106]

Answer:

12

Step-by-step explanation:

Least common multiple means what is the smallest number that both numbers go into

List the prime factors

4= 2*2

12 = 2*2*3

The factors that are in needed to make both are 2 and 3

We need 2 of the 2's and 1 3

2*2*3 = 12

Answer:

y-coordinate is 5 or -1.

Step-by-step explanation:

Point A is at (x, 2) and B is at (x+6, 2). Since AB must lie on the line y=2  and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).

Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).

The area of ΔABC is 6. So,

9 = 1/2 (b)(h)

where b is the base and h is the height.

so b = 6 and h = AC

Solving this for C gives

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.

If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.

Therefore, y-coordinate is 5 or -1.
