1st Method:

(3² -2²) / (3-2)² = (9-4) / (1²) = 5

2nd Method:

(3² -2²) / (3-2)² = (3-2)(3+2) / (3-2)², after simplification by (3-2), the remaining numerator = (3+2) n= 5

Aleksandr-060686 [28]

Answer:

4.2 units

most likely answer choice B

Step-by-step explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

$d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }$

Let's plug in what we know.

$d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }$

Evaluate the parentheses.

$d = \sqrt{(3)^2 + (3)^2 }$

Evaluate the exponents.

$d = \sqrt{(9) + (9) }$

Add.

$d=\sqrt{18}$

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Hope this helps!

Ronnie took a total of 12 quizzes over the course of 2 weeks. How many weeks of school will Ronnie have to attend this quarter b

sashaice [31]

Ok so start with the proportion 12/2 (the number of quizzes per 2 weeks) and set it equal to 18/X (X being the number of weeks that will equal 18 quizzes) after that cross multiply to get 12X=36. divide by 12 to get X=3 weeks
