Answer:
2,640 ft
Step-by-step explanation:
You first find the difference between the two distances, 0.5 miles. One mile is 5280 feet, so
0.5 x 5280 = 2640
The answer is A to change an exponent from negative to positive, just move it into either the numerator or denominator depending on where it is to begin with.
Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area = 
8 = 
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x = 
x = 
x = 
x = 
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.
