Answer:
(6-√21, 6+√21)
Step-by-step explanation:
x^2 - 12x = -15
(x - 6)^2 - 36 = -15
(x - 6)^2 = 21
x - 6 = ± √21
x = 6 ± √21
Answer:
speed = distance÷time 48.7÷1.2 = 40.58
Answer:
755
Step-by-step explanation:
The sum of 308+622+381=755
The map scale is 6 in : 36 mi
simplify it, divide 6 from both sides
6/6 = 1
36/6 = 6
1 in : 6 mi
To find the amount of inches in 52 miles, divide 52 with 6
52/6 = 8.67 (rounded)
8.67 in should be your answer
hope this helps
Answer:
Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.
We can represent this information as:
Therefore, the equation relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
