Step-by-step explanation:
to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term
so, 12/-4 = -3
also, -36/12 = -3
here u see the ratio is always same, i.e., common ratio.
thus u can say it is a geometric series with common ratio -3
Answer:
2(k + 9) = 4
Step-by-step explanation:
Use distributive property.
2 x k = 2k
2 x 9 = 18
Equation:
2k + 18 = 4
Subtract 18 from both sides
2k = -14
Divide both sides by 2
k = -7
|x+8|=5
then x+8= 5 or -5
then x= -3 or -13
Answer: t is 12.5 on a scale drawing
Step-by-step explanation:
since complementary angles always add up to 90 degrees, subtract 90-36 and you get 54
the last one, 54.
