### 20 POINTS AND BRAINLIEST ANSWER: Somebody please help on number 7 & 9. I kind of want to know HOW to do it, so I can complete the rest of the worksheet.

I'm so sorry, I only know what question 7 is talking about:
−14x+2=x−3(Solve Square Root.)
−14x+2=x−3−14x+2=(x−3)2(Square both sides)−14x+2=x^2−6x+9−14x+2(x2−6x+9)=x^2−6x+9(x^2−6x+9)(Subtract x^2-6x+9 from both sides)
−x^2−8x−7=0(−x−1)(x+7)=0(Factor left side of equation)
−x−1=0 or x+7=0(Set factors equal to 0)
x=1 or x=−7Check answers. (Plug them in to make sure they work.)
x=−1(Doesn't work in original equation)
x=−7(Doesn't work in original equation)

For #9...
4(x−3)(1/2)=8
Step 1: Simplify both sides of the equation.
4(x−3)(1/2)=8
Simplify: (Show steps)
2x−6=8
Step 2: Add 6 to both sides.
2x−6+6=8+6
2x=14
Step 3: Divide both sides by 2.
2x2=14
2
x=7
Really hope this helps!!!:)

Pythagoras is A squared + B squared= C squared (C is always the slanted side!!)

So you do 15 squared + 36 squared (which is 225+1296)= C squared.
You add A squared and B squared together (which is 1521) then square route that number to get your distance from original position. Hope this helps :)
