No he did not because 20% of 250 is 50 and there are 90 students not 50 students!! Hope this helped you a lot !!!
Since there are three variables and three constants you add like terms.
3(x+15) = 3x + 40
Answer:
products - -3x and 6x^2
factors - 8 and 2x
Step-by-step explanation:
Sketch the two quadrilaterals and label them as shown in the figure below.
Let x = length of the 4th side of ABCD.
Because ABCD ~ EFGH, therefore
x/5 = 14/6
That is,
x = (5/6)*14 = 11.67 ft
Answer: D. 11.7 ft
The graph is shown below. I used GeoGebra to create the graph. The graph is restricted on the domain
meaning that everything to the left of x = 0 is not drawn, and the same for everything to the right of x = 2.
A table of values is included as well. Each row in the table represents an ordered pair point (x,y) that is on the blue cosine graph.
