Answer:
23.5
Step-by-step explanation:
First the shaded area is 28 but there is a triangle so we have to solve the area of the triangle. (formula for triangle: B x H x 1/2) 3 times 3=9 divided by 2=4.5
28-4.5=23.5
Answer:
-2. Not really sure on this one because there is only one equation, so I think it is impossible.
Step-by-step explanation:
x=4-y
x+y-6
4-6=-2
Answer:
Step-by-step explanation:
Please present these numbers as a list: 7, -21, 63, -189, ....
Otherwise it appears that you are adding them up, which is not the case.
We can tell that this is a geometric series because each new number is -3 times the previous number: -3(7) = -21, -3(-21) = 63, and so on. Let r = -3 and a = first number = 7.
a
The sum of an infinite geometric series exists if and only if |r} < 1. Here, |-3|, or 3, so in this case the sum of the series does not exist. That is, the series diverges.
