Answer:
x = -9
Step-by-step explanation:
Step 1: Write equation
2 + x = -7
Step 2: Solve for <em>x</em>
- Subtract 2 on both sides: x = -9
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
- Substitute: 2 - 9 = -7
- Subtract: -7 = -7
The answer is 2:1.
The centroid separates the median, or the point from the midpoint of a side of a triangle with its opposite angle, at a ratio of 2:1, meaning that one segment is 1/3 the length of the median and the other segment is 2/3 the length of the median.
The equation would be .05x+50=100 Then you would solve for x
I think its perimeter so you do 10x2=20 and 20x2=40 and add 20+40 to get 60 so the answer is 60 cause it says "fencing" which is the outer border
therefore answer is 60 feet
