-6+8x=-38 
move -6 to the right of the exppression 
it become 8 * x -6=-38
8* x -6+38=0
8* x -6 +32=0
Added fractions or integers together 
<span>It becomes 8*x +32=0
</span> 8*x+32=0
Solved <span>linear equation 8*x+32=0 </span>equivalent to 8*x+32 =0 
it becomes 0=0
<span> 
</span>
<span>This is an equation!</span><span> Solutions X=-4</span>

-6 +8x = -38
8x = -32
x = -4
I did this by first adding 6 to both sides to get 8x by itself. I then divided by 8 to get x by itself. I remembered to use the - - + rule (Two negatives make a positive, a positive and a negative make a negative). Hope this helps!

Which number is not a perfect square?
bagirrra123 [75]

Answer:

C

Step-by-step explanation:

If I had to make a choice it would be C. Its strange because all numbers can be divided by 4 so they all can make a square. But the closest was C.

Please help i have 2 questions thank you very much.

Hello!

Question 1
We first have to convert everything to yards since the concrete is charged by the cubic yards

15 feet = 5 yards
15 feet = 5 yards
3 inches = 0.08333

Multiply these to find the volume

5 * 5 * 0.08333 = 2.08325

Multiply this by the cost

2.08325 * 46 = 95.83

The answer is C) $95.83
------------------------------------------------------------------------------------------------------
Question 2

You have to find the volume of the first pyramid

The equation we use is V = \frac{lwh}{3}

V is volume
l is length
w is width
h is height

Put in the values we know

V =  \frac{16 * 16 * 28}{3}

Multiply

V =  \frac{7168}{3}

Divide

V = 2389.3333

Now we use this to find the side length of the second pyramid

2389.333 =  \frac{lw * 112}{3}

Multiply both sides by 3

<span>7167.999 = lw * 112
</span>
Divide both sides by 112

63.9999 = lw

Since it is a square pyramid we know that sides are equal

63.999 = l^2

Take the square root of both sides

8 = l

The answer is B) 8in

Hope this helps!
