7x-2+=6x+2
Move 6x to the other side. Sign changes from +6x to -6x.
7x-6x-2=6x-6x+2
7x-6x-2=2
x-2=2
Move -2 to the other side. Sign changes from -2 to +2.
x-2+2=2+2
x=4
Answer: x=4
Answer:
Given the statement: Square root 300c^9 = 10c^x square root 3 c
⇒![\sqrt{300c^9} =10c^x\sqrt{3c}](https://tex.z-dn.net/?f=%5Csqrt%7B300c%5E9%7D%20%3D10c%5Ex%5Csqrt%7B3c%7D)
Squaring both sides we get;
![(\sqrt{300c^9})^2= (10c^x\sqrt{3c})^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B300c%5E9%7D%29%5E2%3D%20%2810c%5Ex%5Csqrt%7B3c%7D%29%5E2)
Simplify:
![300c^9 = 100c^{2x}(3c)](https://tex.z-dn.net/?f=300c%5E9%20%3D%20100c%5E%7B2x%7D%283c%29)
We know: ![a^m \cdot a^n = a^{m+n}](https://tex.z-dn.net/?f=a%5Em%20%5Ccdot%20a%5En%20%3D%20a%5E%7Bm%2Bn%7D)
then;
![300c^9 = 300c^{2x+1}](https://tex.z-dn.net/?f=300c%5E9%20%3D%20300c%5E%7B2x%2B1%7D)
Divide both sides by 300 we get;
![c^9 = c^{2x+1}](https://tex.z-dn.net/?f=c%5E9%20%3D%20c%5E%7B2x%2B1%7D)
On comparing both sides we have;
![9 = 2x+1](https://tex.z-dn.net/?f=9%20%3D%202x%2B1)
Subtract 1 from both sides we get;
8 = 2x
Divide both sides by 2 we have;
x = 4
Therefore, for the value of x =4 the given statement is true.
Step-by-step explanation:
4 inches less means
April = a
March = a - 4
