Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term 
can be obtained as the previous term 
by a constant value called the common ratio.
or equivalently
Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6
Answer:
21
Step-by-step explanation:
yeah 2+2 is 21 thanks for the very nonexistent question
A (A right triangle with a side length of 5 and hypotenuse with length \sqrt{74})
Answer:
D) 28.762 cm
Step-by-step explanation:
For this case we must find the value of the variable "p" of the following equation:
We apply distributive property on the left side of the equation taking into account that 
and 
:
We add similar terms:
We subtract 
from both sides of the equation:
We subtract 8 from both sides of the equation:
We divide by -6 on both sides of the equation:
