(p² + 3p + 6) + (2p² + 6p + 6)
First you must combine (aka sum) like terms. Like terms are numbers that have matching variables OR are numbers with out variables OR have matching variables with matching exponents. In this case the like terms are p² and 2p² (they both have the exponent p that is squared); 3p and 6p (they both have the variable p attached); and 6 and 6 (both numbers without variables)
(p² + 2p²) + (3p + 6p) + (6 + 6)
3p² + 9p + 12
Hope this helped!

The answer is B) 4:5
First write the ratio out. To find the simplified expression, divide by the greatest common factor (GCF). In this case, the GCF of 28 and 35 is 7.
28:35
--- ----
7 7
=4:5
4:5 is the simplest form because you cannot simplify it further.

Step-by-step explanation:
The number of questions in the test is 30
Step-by-step explanation:
Let's call the total number of questions in the test N.
We know that Laura answered 27 questions, and these 27 questions represent the 90% of the test.
Therefore, we can say that 27 is the 90% of N.
Re-writing the percentage as a fraction,
This means that:
And now we can solve for N to find the number of questions in the test:

<h3>Answer:</h3>
C. 5 – (m + 3)
<h3>Explanation:</h3>
... Five decreased by ⇒ 5 - ___
... the sum of a number and three ⇒ (m+3)
So, the whole word phrase translates to ...
... 5 - (m+3) . . . . . matches selection C.
_____
"the sum of a number and 3" refers to the whole quantity (m+3), which is why we put it in parentheses. In English, the operative phrase is "five decreased by the sum", and the prepositional phrase "of a number and three" describes the content or nature of the sum.
