Answer:
x = - 3 ± √27 or if you want it in decimal form correct to nearest hundredth:
x = -8.20, 2.20.
Step-by-step explanation:
x^2 + 6x - 18 = 0
this will not factor so we use completing the square:
x^2 + 6x = (x + 3)^2 - 9 so:
(x + 3)^2 - 9 - 18 = 0
(x + 3)^2 = 27
x+ 3 = ±√27
x = - 3 ± √27
Answer:
2 to 6 is constant. 14 to 15 is constant. The height characterized by the line remains straight.
Step-by-step explanation:
Looking at the graph, we can identify the x axis which is time, and the y axis which is the height. Now, as the height increases or decreases, so does the line as it goes higher or lower. Now, when the question asks what constant means, it is asking where during the graph is the height the same. We can see that it is the same when the height does not change over time, which is from 2 to 6. The height remains the same, therefore there is no change and the height is constant.
Answer:
x+(x+7)
Step-by-step explanation:
sum=add all together
Answer:
False.
Step-by-step explanation:
it is an angle formed by 2 adjacent sides inside the polygon.
There would be 6 waters and 5 snack mixes. Each water is 1.25, so 1.25x6 would be 7.50. And each snack is 2.50, so 2.50x5 would be 12.50. Adding those two or es together would be exactly $20 and adding all the items is 11. Hope this helps:)
