Find out the length of each side. For the slanty sides, you can do this by using the formula

For the straight sides (like the one on the bottom and the one on the left), just use simple subtraction.
Add up all 4 sides and you get the perimeter. You should get 20, 15,
and
. The total is 35 +
.
Answer:
The 14th term is -58
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
where a1 is the first term
d is the common difference and
n is the term number
a1 = 7
d = 2-7 = -5
Check -3-2 = -5 so d = -5
an = 7 -5(n-1)
We want the 14th term
a14 = 7 -5(14-1)
a14 = 7 -5(13)
a14 = 7 -65
a14 = -58
Answer:
Step-by-step explanation:
Part A
To keep it simple, I will use v instead of vi, x instead of triangle x and t instead of triangle t.
The equation becomes: x = vt + 1/2at^2
Solve for a:
x = vt + 1/2at^2
x - vt = 1/2at^2
(x - vt)*(2/t^2) = 1/2at^2*(2/t^2) = a
a = 2(x-vt)/t^2
or writing in the right format
a = 2(Δx - viΔt) / Δt^2
It's pretty simple
Given: A = 38
B = 75
Solution:
The sum of all angles of a triangle = 180
So,
A + B + C = 180
38 + 75 + C = 180
C = 180 - 113
C = 67
Answer:
No, that answer is not correct. If you split the figure in half you have one line of symmetry. I think that the figure only has one line of symmetry.
