X^2 - 5x - 24
(X - 8)(x + 3)
X = 8 and x = -3
Therefore, the other solution is -3.
y=2x+3 (the 3 can be changed)
Answer:
The answer to your question is:
Step-by-step explanation:
a) There is no figure 0.
b) From one figure to the other there are 2 more cubes
c) Number of cubes = 3 + 2(n- 1)
where n is the number of figure
d)
Number of cubes in figure 100 = 3 + 2(100 - 1)
= 3 + 2(99)
= 3 + 198
= 201
The answer would be -6 or letter B because
Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.
