1. 7x - 28 = 84
2. 7x = 112
3. x = 16
I can conclude that the sign of the other integer is positive and that the other integer is 6 or greater.
I tried explaining it, but failed miserably. I'm so sorry! :(
Answer:
a) ![\sqrt[3]{4096} = 16](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4096%7D%20%3D%2016)
b) 4096/ 4 = 1024
Step-by-step explanation:
If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:

(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).
Now, cross multiply and solve for x:
28x+14=30x
<em>*Subtract 28x from both sides to isolate the variable*</em>
14=2x
<em>*Divide both sides by 2*</em>
7=x
Hope this helps!!
