The rest station is the midpoint of the given coordinates:
(-20+35)/2 , for the x value and (15+-12)/2 for the y value.
Coordinates of the rest station: (7.5, 1.5)
How far is the destination? Use the distance formula : D² = √(x1-x2) + (y1-y2)
(-55)² + (27)² = D² D = √3754 = 61.27
48 * 5 = 240
240 / 32 = 7.5 gallons a week ( $28.42)
Answer:
x = 8
Step-by-step explanation:
( 6x + 1 ) + 90 + ( 5x + 1 ) = 180
6x + 1 + 90 + 5x + 1 = 180
11x = 88
x = 8
There u just needed to search the formula
Answer:
The second choice is the correct one.
Step-by-step explanation:
20x^4 - 45x^2
GCF is 5x^2, so the factors are:
5x^2( 4x^2 - 9)
Now 4x^2 - 9 is the differencr of 2 squares:
4x^2 - 9 = (2x + 3)(2x - 3)>
