Answer/Step-by-step explanation:
[1] x+9+1+3x
Add the numbers
x + 10 +3x
Combine like terms
4x+10
Common factor
2(2x+5)
<u>Solution = </u><u>2(2x+5)</u>
<u>.............................................................................................................................................</u>
[2] 5a+6c+2a+3c
Combine like terms
7a+6c+3c
Combine like terms
7a+9c
<u>Solution</u><u> = 7a + 9c</u>
<u>...............................................................................................................................................</u>
[3] 5n+6m+3n
Combine like terms
8n + 6m
Rearrange terms
6m + 8n
<u>Solution </u><u>= 6m+8n</u>
<u>.............................................................................................................................................</u>

Divide both sides by their LCD, 2
2/4 = 1/2
1/2 is irreducible
Answer:
19.3%
Step-by-step explanation:
Assuming the events are independent, the probability of all five is ...
0.72^5 ≈ 0.19349 ≈ 19.3%
Answer:
14
Step-by-step explanation:
Trust me, I had the same thing like this. It's 14/b.
Expand
-x^2+12x+189
now
the axis of symmetry is -b/2a for ax^2+bx+c
so
-1x^2+12x+189
a=-1
b=12
-b/2a=-12/(2*-1)=-12/-2=6
the axis of summetry is x=6
