30 + 25m = 80 + 15m
25m - 15m = 80 - 30
5m = 50
m = 10
Multiply each throughout!
=x^2+6x+8x+48
then arrange accordingly
x^2+14x+48
remember that in quadratic equation that you should have a squared (a) variable and a coefficient(b) and just a raw value (c)
It is true because the volcano is expelling magma which is what you see in real life
Answer:
D
Step-by-step explanation:
Answer:
d. 20+10+5+2.5+...
Step-by-step explanation:
No geometric series with a common ratio of magnitude greater than 1 will have a finite sum. Nor will any arithmetic series.
Those descriptions exclude answer choices a, b, c. Choice d is a geometric series with a common ratio of 1/2, so will have a finite sum. (It is 40.)
