Step-by-step explanation:
6 squared, 7 squared, 8 squared makes 149
Answer:
the distance is 16
Step-by-step explanation:
Hi there!
We are given point A (-4,-13) and point B (-4,3). We need to find the distance between those two points
the distance formula is given as
where (
,
) and (
,
) are points
we are given 2 points, which is what we need for the formula. However, let's label the values of the points to avoid any confusion
=-4
=-13
=-4
=3
now substitute those values into the formula. Remember: the formula uses SUBTRACTION.
![\sqrt{(-4--4)^2+(3--13)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4--4%29%5E2%2B%283--13%29%5E2%7D)
simplify
![\sqrt{(-4+4)^2+(3+13)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4%2B4%29%5E2%2B%283%2B13%29%5E2%7D)
now add the values inside the parenthesis that are under the radical
![\sqrt{(0)^2+(16)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%280%29%5E2%2B%2816%29%5E2%7D)
raise everything under the radical to the second power
![\sqrt{0+256}](https://tex.z-dn.net/?f=%5Csqrt%7B0%2B256%7D)
add under the radical
![\sqrt{256}](https://tex.z-dn.net/?f=%5Csqrt%7B256%7D)
now take the square root of 256
=16
so the distance between point A and point B is <u>16</u>
Hope this helps! :)
Answer:
x=34
Step-by-step explanation:
x+(x+12)+(100) = 180
2x+112=180
x=68
x=34
Answer:
see explanation
Step-by-step explanation:
the sum to n terms of an arithmetic sequence is
=
[2a + (n - 1)d ]
where d is the common difference and a is the first term
here d = 9 - 7 = 7 - 5 = 2 and a = 5, hence
=
[(2 × 5) + 2(n - 1) ]
=
(10 + 2n - 2)
=
(2n + 8)
= n² + 4n
When sum = 165, then
n² + 4n = 165 ← rearrange into standard form
n² + 4n - 165 = 0 ← in standard form
(n + 15)(n - 11) = 0 ← in factored form
equate each factor to zero and solve for n
n + 15 = 0 ⇒ n = - 15
n - 11 = 0 ⇒ n = 11
but n > 0 ⇒ n = 11
Answer:
14. -g + 10, 15. 12k + 3
Step-by-step explanation:
I'm assuming you want to simplify the equation. For 14, we distribute -2. This gets us -2g + 10 + g. We can simplify that to -g + 10. We can't simplify that, so our answer is complete. For 15, we combine 8k and 4k to get 12k + 3. That can't be simplified, so we are done.
