Answer:

6825 in

Step-by-step explanation:

Since the shape is a composite figure, we need to break it up into 2 shapes!

Rectangle and a triangular prism

Solving for Rectangle...

Volume = Length · Width · Height

Volume = 30 · 13 · 13

Volume = 5070 in

Solving for Triangular Prism

Volume = Length · Width · Height / 2

Volume = 30 · 9 · 13 / 2

Volume = 3510/2

Volume = 1755 in

Finally, add the volumes!

5070 + 1755 = 6825 in

Tobin is solving the equation 3(x - 1.25) = 11.25. His work is shown below.
castortr0y [4]

Answer: In the last steps, instead of multiply each side by 3, he has to divide each side by 3.

Step-by-step explanation:

Hi, Tobin makes the mistake in the last steps.

3(x-1.25) = 11.25  

3x-3.75= 11.25  

3x-3.75+3.75= 11.25+3.75  

3x = 15

Until this step is the work ok.

Now, instead of multiply each side by 3, he has to divide each side by 3:

So:

3x /3 = 15/3

x = 5

Feel free to ask for more if needed or if you did not understand something.

PLEASR HELP MEEEE ASAP​
Naddika [18.5K]

Answer:

A: Yes, I agree. Why? Because if you look at the shape, its a triangle right, and a triangle both sides are equal, while the bottom line is not. But because both sides are equal, and half of the triangle is MPN and the other side is QPN, they both are congruent (or equal to)

B: Like I said, both MPN and QPN are both equal, and if you remove the P, it would still be the same because the shape has not changed.

I hope I helped :)
