3 0

Answer:

Area of a triangle = bh/2

Area of a rectangle = bh

The area of the triangles are the same, the area of the rectangles are the same.

triangle: 9x8/2

72/2 = 36

Rectangle: 8x14=112

There are 2 triangles and 3 rectangles so,

2(36)+3(112)

72+336= 408 in²

Answer:

figure skates will be $1 cheaper.

Explanation:

<u>given equation</u>:

  • to rent figure skates : f(x) = 1.50x + 2
  • to rent hockey skates : h(x) = 2x +1.5

<u>solve for rent of figure skates</u>:

f(x) = 1.50x + 2.00

f(3) = 1.50(3) + 2.00

f(3) = 6.5

<u>solve for rent of hockey skates</u>:

h(x) = 2x + 1.5

h(3) = 2(3) +1.5

h(3) = 7.5

<u>cheaper - figure skates than hockey skates</u>:

$7.5 - $6.5

$1

Compare and contrast the perpendicular bisectors and angle bisectors of a triangle. How are they alike? How are they different?
AleksandrR [38]

<span>1 perpendicular bisector divides 1 side of the triangle into two equal lengths at a 90 degree angle. So if there's is three perpendicular bisectors, then it splits all three sides the triangles into equal lengths.

Angle bisectors splits an angle of a triangle into two even degrees.  
 </span>

<span>
</span>

<span>EX: if it is an equilateral triangle, each angle will be sixty degrees. Therefore, ONE angle bisector will split ONE of the angles into even degrees of thirty degrees. </span>
