I would say A (7) but I’m not 100% sure.
To factor a polynomial we need to find 2 numbers that add up to -15 and multiply into -54.
(-x -18)(x +3) Will be your answer.
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve
Answer:
71th term is 141
Step-by-step explanation:
1 + (n - 1)*2 = 141 {Use distributive property}
1 + 2n - 2 = 141
2n - 1 = 141
2n = 141 + 1
2n = 142
n = 142/2
n = 71
It would be:1/x = 1/40+1/52 = 13+10/520 = 23/520
x = 520/23 = 22.60 minutes
