Hello :
<span>the nth term of a geometric sequence is :
Un = Up ×r^(n-p) . r is the common ratio
for : p=5 and n= 2
U5 = U2 ×r^3
16 = -2 r^3
r^3 = -8
but : -8 = (-2)^3
so : r = -2
Un = U2 × r^(n-2)
Un = -2 ×(-2)^(n-2)= (-2)^(n-2+1)
</span><span>the nth term of a geometric sequenceis : Un = (-2)^(n-1)</span>
Hi, there!
_____
To find the missing side length of this triangle (which is a <em>right</em> triangle), we'll use Pythagoras' Theorem.

Here,

Hypotenuse (the longest side): c
We know that

So, we can substitute our parameters, and solve for c.
square 2 and 28
add the numbers
square root both sides

Hope the answer - and explanation - made sense,
happy studying!!
Answer:
x = -2
Step-by-step explanation:
Solve -6x = 5x + 22
add 6x to both sides
0 = 6x + 5x + 22
0 = 11x + 22
11x = -22
x = -22/11
x = -2
Answer:
7
Step-by-step explanation:
M = (L + S)
24/2 = 12
12-5 =7
L:5
S:7
7+5 = 12 (Manjit)
12+12= 24
Answer:
c
