Answer:
kelly drove 55 miles in one hour because if you divide 440 by 8 you get 55 and alberto drove 52 so kelly drove the farthest and she drove 3 mils further
Step-by-step explanation:
The perimeter of the figure is 20.73 cm.
<h3>What is perimeter:</h3>
Perimeter is a closed part that surrounds a two dimensional or one length figure.
The perimeter of the figure above is the sum of the wholes sides. In other word the sum that surrounds the whole sides.
Therefore, the perimeter of the figure is as follows:
perimeter = 3.1 + 5.2 + 4.24 + 2.19 + 6
perimeter = 8.3 + 4.24 + 2.19 + 6
perimeter = 12.54 + 2.19 + 6
perimeter = 14.73 + 6
perimeter = 20.73 cm
Therefore, the perimeter of the figure is 20.73 cm.

Answer:
- <u>B) A = 2x² - 8x + 8</u>
Step-by-step explanation:
<u>Area of a triangle</u>
Here,
<u>Solving</u>
- A = 1/2 (2x - 4) (2x - 4)
- A = 1/2 (2x - 4)²
- A = 1/2 (4x² - 16x + 16)
- <u>A = 2x² - 8x + 8</u>
Answer:
BC = 23
Step-by-step explanation:
Since ∠ A = ∠ C then the triangle is isosceles with AB = BC, that is
3x + 14 = x + 20 ( subtract x from both sides )
2x + 14 = 20 ( subtract 14 from both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Thus
BC = 3x + 14 = 3(3) + 14 = 9 + 14 = 23
