D = √(y2-y1)² + (x2-x1)²
d = √(-3+19)² + (-2+12)²
d = √16² + 10²
d = √256 + 100
d = √356
d = 18.87 units
In short, Your Answer would be: 18.87 units

Answer:
Step-by-step explanation:
This is a division problem. We need to divide the pounds in a bag by the weight of 1 brick in order to find the number of bricks in a bag.
3 1/3 / 5/6
---Make the mixed number an improper fraction
10/3 / 5/6
---Multiply the first fraction (10/3) by the reciprocal of the second fraction (5/6). The reciprocal is essentially the opposite and is found by "flipping" the fraction.
10/3 x 6/5
60 / 15
4
Answer: 4 bricks are in the bag

This is the order you need to use to solve this problem: PEMDAS
(Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
So you start with P and make your way down to S
(2x + 3)(x - 6) - 2x² + 3x + 30 First multiply (2x + 3)(x - 6) (distribute)
(2x)x - (2x)6 + (3)x - (3)6 = 2x² - 12x + 3x - 18 = 2x² - 9x - 18
(2x²- 9x - 18) - 2x² + 3x + 30 Simplify by combining like terms
-6x + 12
