The length would be 14ft and the width would be 6ft

The answer is the width is equal to 14 and the length is equal to 6.
To check this subtract 14 from 6 and that gives you 8.
Multiply 14 and 6 together that gives you 84.

Hope this helps!!:)

The given equation has no solution when C is equal to what number?<br><br> 2x+C(8+x)=16
3241004551 [841]

Answer:

-2

Step-by-step explanation:

When C=-2, the variable x will be removed from the equation (2x-2x=0). Therefore, we are left with -16\neq 16. Thus, when C=-2, the given equation has no solutions.

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.
vampirchik [111]

Answer:

the "negative solution" is -3

Step-by-step explanation:

Represent the number by n.

Then n^2 - 24 = 5n

We rewrite this in standard quadratic form:

n^2 - 5n - 24 = 0

This factors as follows;  (n + 3)(n - 8) = 0

The roots are n = -3 and n = 8.  Thus, the "negative solution" is -3

The sculpture consists of five identical prisms. JD says the surface area of the sculpture is 44 times the surface area of one p
larisa86 [58]
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>
