Answer: -5
Step-by-step explanation:
You should get negative 5 because first you multiply and add a sign.
So for this question, you needed to add a negative sign because there are 2 negative signs and 1 positive. ( -,-,+) so if you do -1 x5, sinse you used one negative sign for the -1 and a positive sign for 5, you are left with a negative sign. So that is why you need to add a negative sign before our answer 5. on this question.
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:

Let's plug in what we know.

Evaluate the parentheses.

Evaluate the exponents.

Add.

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!
3 because 20/6=3.3333333333 so you would have 3 because you can split the pictures
sqrt 7 ( sqrt 14 + sqrt 3 )
distribute
sqrt(7) sqrt(14) +sqrt(7) *sqrt(3)
sqrt(98) + sqrt(21)
sqrt(49*2) + sqrt(21)
sqrt(49) * sqrt(2) + sqrt(21)
7sqrt(2) + sqrt(21)
