The complete question in the attached figure

we know that
(see the attached figure n 2 to understand the problem)
[the surface area of one prism]=2*[x*x]+2*[x*y]+2*[x*y]----> 2x²+4xy
[the surface area of the sculpture]=2*[5*x*y]+2*[3*x*x]+2*[3*x*y]--> 6x²+16xy

now
<span>JD says the surface area of the sculpture is 4 times the surface area of one prism
</span>[the surface area of the sculpture]=4*(2x²+4xy)---> 8x²+16xy

we compare the value that JD says with the real value
(8x²+16xy) > (6x²+16xy)
the value that JD says is <span>greater in comparison with the real value
</span>This is because <span>JD should also subtract the areas of eight hidden surfaces.

the answer is 
</span>JD should also subtract the areas of eight hidden surfaces<span>

</span>

Answer:

x=\frac{179}{3}

Step-by-step explanation:

We are solving for x in the equation:

3x+56=235

First, isolate the variable term by subtracting 56 from both sides of the equation:

3x=179

Now, divide both sides of the equation by the coefficient of x:

x=\frac{179}{3}

This solution for x, as a decimal, would be non-terminating. If you divided 179 into 3, you would get the non-terminating decimal of:

59.66666...

Therefore, our solution is:

x=\frac{179}{3}

-

We can check our solution by substituting \frac{179}{3} for x in the initial equation:

3x+56=235

Substitute:

3(\frac{179}{3} )+56=235

Simplify 3(\frac{179}{3} ):

179+56=235

Add:

235=235

Since both sides of the equation are equal, our solution is correct!

Anni [7]
The loan proceeds will be given as follows:
A=P(1+r/100)^n
Plugging the values we obtain
n=4 months=
A=1000(1+12/3*100)^1
A=$1040
hence the proceeds will be:
1040-1000=$40
