This is how I learned.
Place a point above the line segment. Open the compass so that you can create arcs on the line segment. One arc should intersect on the right side, the other on the left. Name these points (A and B, for example). Move the compass to one point. Use the same radius in the compass<em /><em /> and make an arc below the line segment. Then move the compass to the opposite point and make another arc (with the same radius). The two arcs should intersect. Draw a line from the point above the line segment to the new intersection and you have your perpendicular bisector.
That is 62x9 which is 9x2=18 and 9x60=540 so you then add 540+18=558 chairs
Answer:
2
Step-by-step explanation:
let 'x' = number
x³ - x² = 2x
x³- x² - 2x = 0
x(x² - x - 2) = 0
x(x - 2)(x + 1) = 0
x = -1, 0, 2
the only positive solution is the number 2
Answer: 10 , 13 , 14 , 15
Step-by-step explanation:
To find the perimeter of a quadrilateral , we will add all its side , that is
Perimeter = x + x + 3 + x + 4 + x + 5
That is
52 = x + x + 3 + x + 4 + x + 5
52 = 4x + 12
subtract 12 from both sides
40 = 4x
divide through by 4
x = 10
therefore , the lengths of the sides are
10 , 10+3 , 10 + 4 , 10 + 5 , that is
10 , 13 , 14 , 15
