x(a + 1 + 4)
x(a) + x(1) + x(4)
ax + x + 4x
The number must be distributed across every term.
X-5=2-3x+9
x-5=-3x+11
4x-5=11
4x=16
x=4
Answer:

Step-by-step explanation:
EF and JK are similar, and the other side we know, FG, is similar to KL. From there, just put them into a ratio!


Answer:
9 and 12
Step-by-step explanation:
3n - 1
When n = 1,
3n - 1 = 3*1 - 1 = 3 -1 = 2
When n = 2,
3n - 1 = 3*2 - 1 = 6 -1 = 5
When n = 3,
3n - 1 = 3*3 - 1 = 9 -1 = 8
Hence, the first three terms are 2, 5 and 8.
