(3x+4)(2x+1)
If the question asks you to find roots/solutions:
3x + 4 = 0
3x = -4
x = -1.33333333
2x + 1 = 0
2x = -1
x = -0.5
Start with
Multiply both sides by 15 to get rid of denominators:
Expand the left hand side:
Move all terms involving x to the left and all numbers to the right:
Sum like terms:
Divide both sides by -4:
Although the points do not sit exactly on integer coordinates, we can round their coordinates and say that
Now, remember that the first coordinate represents the number of events, and the second coordinate represents the number of stamps. So, if we want the number of events to be four times the number of stamps, we need a point whose first coordinate is four times the second.
This is the case for point C, because its first coordinate is about 20, and its second coordinate is about 5, and 20 is four times 5.
Answer:
29 degrees
Step-by-step explanation:
x + 61 = 90
x = 90 - 61
x = 29
