30 divided by 12 equals 2.5 so it should equal 2.5%

12 out of 30 students are boys, so you can also say 12/30. 12/30 simplified is 4/10, or 40%.

Im being timed! HURRYYYYYYYYY simplify:

Answer:

B. $p^2+p-11$ .

Step-by-step explanation:

Step 1:

$((((3+(4*(p^2)))-5p)-3p^2)+4p)+8$

Step 2:

$((((3 + 22p^2) - 5p) - 3p^2) + 4p) + 8$

Step 3:

Factoring $p^2-p+11$
The first term is, $p^2$ its coefficient is 1 .
The middle term is, -p its coefficient is -1 .
The last term, "the constant", is +11
Step-1 : Multiply the coefficient of the first term by the constant 1 • 11 = 11
Step-2 : Find two factors of 11 whose sum equals the coefficient of the middle term, which is -1 .
-11 + -1 = -12
-1 + -11 = -12
1 + 11 = 12
11 + 1 = 12
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Final Solution:

$p^2 + p - 11$
